Hello Mistyann!

First you need to know amount of barium phosphate is

Half of potassium phosphate, also 2.18 mol.

Molar mass of Barium phosphate is 3·137.2 + 2·(30.97+4·16) g/mol

You can calculate it yourself dear.

Now mass is amount of substance · molar mass.

It has been an honour to teach you, dear,

God bless!

The coefficients are: 1, 2, 1, 2

Answer: the answer is 12M

Explanation: 3.0mol/ 0.25L =12M

12M is the molarity of a solution made from dissolving 3.0 moles of Saline (NaCl) in 0.25 L of solution.

The amount of molecules of molecules divided by the quantity of liters in solution is the definition of molarity, a concentration unit in chemistry. It is crucial to comprehend how it is calculated as well as when to employ it in comparison to other units because it is among the most widely used concentration units.

A chemical solution's concentration is measured in molarity (M). It refers to the solute's moles per liter of solution. To be clear, this is not the same as the liters of solvents (a common mistake).

molarity = number of moles of solute/ volume of solution in litre

molarity =3.0mol/ 0.25L

             =12M

Therefore, 12M is the molarity of a solution made from dissolving 3.0 moles of Saline (NaCl) in 0.25 L of solution.

Explanation:

Answer: 44.706g Al2O3

Explanation:

4A1 + 302 → 2Al2O3

3×(16×2) 2{(27×2)+(16×3)}

= 96 = 204

So

To produce 204g of Al2O3,We need . 96g of O2

To produce 1g of Al2O3,We need

. (96÷204)= 0.47g of O2

To produce 95g of Al2O3,We need

. (0.47×95)= 44.706g of O2

.

So, 44.706 grams of oxygen (O2)

are needed to produce 95 grams of

aluminum oxide (Al2O3).

Explanation:

Answer: approximately 15.1 grams.

Explanation: The key to chemistry is to change everything to moles. Then when you have the answer in moles change the answer back to grams, liters, or whatever you want. Change 25 grams of potassium chlorate to moles. Chlorate is Cl with 3 oxygens. ate = saturated. Chlorine has seven valance electrons when it is saturated six of these electrons are used by oxygen ( 2 electrons per oxygen) leaving only 1 electron. 1 K x 39 grams/mole+1 Cl x 35.4grams/ mole+3 O x 16 grams/ mole = 122.4 grams / mole Potassium Chlorate 25 122.4 = moles. 2.05 moles of Potassium Chlorate. There is a 1:1 mole ratio. 1 mole of Potassium Chlorate will produce 1 mole of Potassium Chloride. 2.05 moles of Potassium Chlorate will produce 2.05 moles of Potassium Chloride. Find the gram molecular mass of Potassium Chloride. 1 K x 39 = 39+1 Cl x 35.4 = 35.4 = 74.4 grams / mole. 2.05 moles x 74.4 grams/ mole = 15.2 grams

The mass of O₂ that will be form is 9.8 grams

The chemical reaction is as follows:

2KClO₃ → 2KCl + 3O₂

From the reaction 2 moles of potassium trichlorate decompose to form 2 moles of potassium chloride and 3 moles of oxygen.

Therefore,

molar mass of KClO₃ = 39 + 35.5 + 48 = 122.5 grams

molar mass of O₂ = 32 grams

Therefore,

2(122.5) g of  KClO₃ produces 3(32) grams of O₂

25 g of KClO₃ will produce ? grams of  O₂

cross multiply

mass of O₂  produced = 96 × 25 / 245

mass of O₂  produced = 2400 / 245

mass of O₂  produced = 9.7959

mass of O₂  produced ≈ 9.8 grams

Explanation:

Molality = moles of solute/mass (in kg) of solvent

The solute here is NaCl, of which you have 40 g or 40/58.4428 = 0.6844 moles NaCl.

The solvent here is water, of which you have 1500 g or 1.500 kg H2O.

The molality of the resulting solution would thus be 0.6844 moles NaCl/1.500 kg H2O = 0.4562 mol/kg.

If you have to consider sig figs, then your final answer would have one sig fig (40 g has one sig fig). In that case, your final answer would be 0.5 mol/kg.

Answer:

Dividing the mass of the water lost by the original mass of hydrate used is equal to the fraction of water in the compound. Multiplying this fraction by 100 gives the percent water in the hydrate.

Explanation:

The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.

The proportion of matter that makes up an object is quantified by its mass. The kilogram, or kg, would be the fundamental SI unit of mass.

Any substance that contains water through the form of H2O molecules is referred to as a hydrate. This water content by weight can vary, but it is typically fixed. The most well-known hydrates seem to be crystalline solids which decompose once the attached water is removed.

Therefore , The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.

Answer: 0.16 g H2

Explanation:

Mg+ H2SO4= MgSO4 + H2

Atomic massof Mg is 24

Molecular mass of H2 is 2

So,

24g Mg produce 2 g H2

1g Mg produce (2÷24)= 0.083 g H2

2.00g Mg produce (0.083×2) g H2

   = 0.16 g H2

 0.16g of hydrogen is formed when 2.00g of magnesium.

The mass of hydrogen gas formed when 2.00g of magnesium is equal to 0.165 g.

The chemical equation of a reaction is said to be a balanced equation when the number of atoms of substances is equal on either side of the equation.

Evergy balanced chemical equation must follow the law of conservation of mass according to which the total mass of the substances present on the reactant side should be equal to the total mass of substances present on the product side.

Given, the balanced chemical equation of the reaction of Mg and sulfuric acid:

[tex]Mg + H_2SO_4 \longrightarrow MgSO_4 +H_2[/tex]

One mole of magnesium produces hydrogen gas = 1mol

Given the mass of magnesium = 2g

The number of moles of Mg = 2/24.3 = 0.082 mol

Then the number of moles of hydrogen gas formed = 0.082 mol

The mass of the hydrogen gas = 0.082 × 2 = 0.165 g

Answer:

a) 226.6 grams of Cl₂

b) 19.2 grams of C

c) 303.2 grams of TiCl₄ and 70.4 grams of CO₂

Explanation:

The balanced chemical reaction is the following:

TiO₂(s) + C(s) + 2 Cl₂(g) → TiCl₄(s) + CO₂(g)

(a) What mass of Cl₂ gas is needed to react with 1.60 mol TiO₂?

From the chemical equation, 1 mol of TiO₂ reacts with 2 moles of Cl₂. So, the stoichiometric ratio is 2 mol Cl₂/1 mol TiO₂. We multiply this ratio by the moles of TiO₂ we have to calculate the moles of Cl₂ we need:

1.60 mol TiO₂ x 2 mol Cl₂/1 mol TiO₂ = 3.2 mol Cl₂

Now, we convert from moles to mass by using the molecular weight (MW) of Cl₂:

MW(Cl₂) = 35.4 g/mol x 2 = 70.8 g/mol

mass of Cl₂= 3.2 mol x 70.8 g/mol = 226.6 g

Therefore, 226.6 grams of Cl₂ are needed to react with 1.6 mol of TiO₂.

(b) What mass of C is needed to react with 1.60 mol of TiO₂?

From the chemical equation, 1 mol of TiO₂ reacts with 1 moles of C(s). So, the stoichiometric ratio is 1 mol C/1 mol TiO₂. We multiply this ratio by the moles of TiO₂ we have to calculate the moles of C(s) we need:

1.60 mol TiO₂ x 1 mol C(s)/1 mol TiO₂ = 1.60 mol C(s)

So, we convert the moles of C(s) to grams as follows:

MW(C) = 12 g/mol

1.60 mol x 12 g/mol = 19.2 g C(s)

Therefore, a mass of 19.2 grams of C is needed to react with 1.60 mol of TiO₂.

(c) What is the mass of all the products formed by reaction with 1.60 mol of TiO₂?

From the chemical equation, we can notice that 1 mol of TiO₂ produces 1 mol of TiCl₄ and 1 mol of CO₂. So, from 1.60 moles of TiO₂, 1 mol of each product will be produced:

1 mol TiO₂/1 mol TiCl₄ ⇒ 1.60 mol TiO₂/1.60 mol TiCl₄

1 mol TiO₂/1 mol CO₂ ⇒ 1.60 mol TiO₂/1.60 mol CO₂

Finally, we convert the moles to grams by using the molecular weight of each compound:

MW(TiCl₄) = 47.9 g/mol Ti + (35.4 g/mol x 4 Cl) = 189.5 g/mol

1.60 mol x 189.5 g/mol = 303.2 g

MW(CO₂) = 12 g/mol C + (16 g/mol x 2 O) = 44 g/mol

1.60 mol x 44 g/mol = 70.4 g

Therefore, from the reaction of 1.60 mol of TiO₂ are formed 303.2 grams of TiCl₄ and 70.4 grams of CO₂.
