0.0395 mol NaCl

Explanation:

¡Hola!

En este caso, es necesario para nosotros considerar que las relaciones masa-mol se desarrollan teniendo en cuenta las masas molares de los compuestos involucrados en el sistema. Ahora, dado que este sistema se compone de NaCl, cloruro de sodio como sal de mesa, es posible saber que la masa molar de este es alrededor de 58.44 g/mol.

De esta manera, las moles en 2.31 g se calculan como sigue:

[tex]=2.31gNaCl*\frac{1molNaCl}{58.44gNaCl}\\\\=0.0395molNaCl[/tex]

How many moles of solute are in 9.03 M solution with 15.8 L of solution?

Answer: [tex]m=0.1625\ kg,\ ,V=125\ L[/tex]

Explanation:

Given

The length of the box is [tex]a=0.5\ m[/tex]

1 liter of air has a mass of 1.3 gm

So, the density of air is [tex]1.3\ g/L[/tex]

The volume of the box is

[tex]\Rightarrow a^3=0.5^3\\\Rightarrow 0.125\ m^3\ or\ 125\ L[/tex]

Mass of air in the box is

[tex]\Rightarrow m=\rho \times V\\\Rightarrow m=1.3\times 125\\\Rightarrow m=162.5\ gm\ or\ 0.1625\ kg[/tex]

Answer:

Tri.

Explanation:

''Tri'' is the Greek prefix used to represent the CH3 because there are three hydrogen atoms to form the covalent compound so in Greek method ''Tri'' is used for three. In Greek system, there are certain names for prefixes such as ''di'' is used for two, ''tri'' is used for three, ''tetra'' is used for four etc. This method only provides information about the number of atoms that form the covalent compound.

Explanation:

Answer: The concentration of KOH is 0.1 M.

Explanation:

Given: Mass of KHP = 413 mg (1 mg = 0.001 g) = 0.413 g

Volume of KOH = 20.05 mL

Volume of solution = 41 mL

The molecular mass of KHP is 204.22 g/mol

Hence, moles of KHP are calculated as follows.

[tex]No. of moles = \frac{mass}{molar mass}\\= \frac{0.413 g}{204.22 g/mol}\\= 0.002 mol[/tex]

As molarity is the number of moles of a substance present in a liter of solution.

So, molarity of the given solution is as follows.

[tex]Molarity = \frac{no. of moles}{Volume (in L)}\\= \frac{0.002 M}{0.041 L}\\= 0.0493 M[/tex]

When the given solution is titrated with KOH then concentration of KOH is calculated as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula.

[tex]M_{1}V_{1} = M_{2}V_{2}\\0.0493 M \times 41 mL = M_{2} \times 20.05 mL\\M_{2} = \frac{0.0493 M \times 41 mL}{20.05 mL}\\= 0.1 M[/tex]

Thus, we can conclude that the concentration of KOH is 0.1 M.

Answer:

pH = 4.45

Explanation:

We need to find the pH of [tex]3.5\times 10^{-5}\ M[/tex] solution of HCl. We know that, pH of a solution is given by :

[tex]pH=-log[H]^+[/tex]

Put all the values,

Answer:

K = 6.25x10⁻⁴

Explanation:

Based on the reaction:

SO₂ + 1/2 O₂ ⇄ SO₃ Kp = 2.5x10⁻²

We can find the Kp of a similar reaction using Hess's law where the sum of 2 reactions a and b produce a K that is:

K = Ka*Kb

The sum of twice the reaction of the problem:

SO₂ + 1/2 O₂ ⇄ SO₃

+ SO₂ + 1/2 O₂ ⇄ SO₃

2SO₂ + O₂ ⇄ 2SO₃

Where K must be:

K = Kp*Kp = Kp²

K = (2.5x10⁻²)²

Answer:

Na3PO4+3HCl —> H3PO4+3NaCl

The reaction type for this equation is a double displacement or acid-base reaction, where Na₃PO₄ and HCl exchange ions to form H₃PO₄ and NaCl.

A double displacement reaction is a type of chemical reaction in which the cations and anions of two different compounds exchange places, producing two new compounds. Double displacement reactions are also known as double replacement, metathesis, or ion-exchange reactions.

To balance the equation, you need to make sure that the number of atoms of each element is equal on both sides of the equation. Here is one possible balanced equation:

2Na₃PO₄+ 6HCl → 2H₃PO₄ + 6NaCl

In this balanced equation, there are:

6 sodium atoms (Na) on both sides

2 phosphorus atoms (P) on both sides

12 oxygen atoms (O) on both sides

6 hydrogen atoms (H) on both sides

Note that you can also write the equation in terms of formulas instead of names:

Na₃PO₄ + 3HCl → H₃PO₄ + 3NaCl

Both equations represent the same chemical reaction, but the second one is more concise.

Answer:

Any atom with six protons, regardless of how much other stuff it has, is a carbon atom. Having 7 neutrons, this would be an atom of Carbon 13 (C-13), a stable isotope of carbon making up 1.1% of natural carbon in the atmosphere and near the Earth's surface. As for the electrons, Carbon has six, but atoms may temporarily pick up or lose electrons in the hurly burly of chemical reactions, solar radiation and so forth. This is a negative ion of C13, which will soon pass on its extra election to an atom which needs it (a positive ion).

Answer:

110.92 g

Explanation:

Amount of Ni2O3 consumed= 55.3/59 =0.94 moles

From the reaction equation;

2 moles of Ni2O3 yields 4 moles of Ni

0.94 moles yields 0.94 moles * 4/2

= 1.88 moles of Ni2O3

Mass of 1.88 moles of Ni2O3 = 1.88 moles of Ni2O3  *  59 gmol-1 = 110.92 g

Explanation:

Convert 1.98 grams of PbSO₄ to molecules.

Step 1: Given data

Mass of PbSO₄: 1.98 g

Step 2: Calculate the number of moles corresponding to 1.98 g of PbSO₄

The molar mass of PbSO₄ is 303.26 g/mol.

1.98 g × 1 mol/303.26 g = 6.53 × 10⁻³ mol

Step 3: Calculate the number of molecules in 6.53 × 10⁻³ moles of PbSO₄

To convert moles to molecules, we need a conversion factor: Avogadro's number. There are 6.02 × 10²³ molecules of PbSO₄ in 1 mole of molecules of PbSO₄.

6.53 × 10⁻³ mol × 6.02 × 10²³ molecules/1 mol = 3.93 × 10²¹ molecules

Explanation:

Let us recall that;

[H^+] [OH^-] = 1 * 10^-14

Where;

[OH^-] = 1 x 10^-11

Then;

[H^+] = 1 * 10^-14/1 x 10^-11

[H^+] = 1 * 10^-3

pH = -log [H^+]

pH = -log(1 * 10^-3)

pH = 3

Also;

pH + pOH = 14

pOH = 14 - pH

pOH = 14 -3
