Stu Dent wants to create a salt water solution. He uses 0.614 moles of salt and 182 milliliters of water. What is the molarity of the solution?

Type your answer...

Answers

Answer: The molarity of solution is 3.37 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]

where,

n = moles of solute = 0.614

[tex]V_s[/tex] = volume of solution in ml = 182 ml

Now put all the given values in the formula of molarity, we get

[tex]Molarity=\frac{0.614\times 1000}{182}=3.37M[/tex]

Therefore, the molarity of solution is 3.37 M

Gaseous ethane CH3CH3 reacts with gaseous oxygen gas O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. What is the theoretical yield of carbon dioxide formed from the reaction of 1.8g of ethane and 4.6g of oxygen gas?

Answers

Answer:

mass of CO₂ produced = 5.06 g of CO₂

Explanation:

Equation of the reaction: 2CH₃CH₃ + 5O₂ ---> 4CO₂ + 6H₂O

From the equation of the reaction, 2 moles of gaseous ethane reacts with 5 moles of oxygen gas to produce 6 moles of water.

molar mass of ethane = 30 g/mol

molar mass of oxygen gas = 32 g/mol

number of moles of ethane present in 1.8 g = 1.8/30 = 0.06 moles

number of moles of oxygen gas present in 4.6 g = 4.6/32 = 0.14375 moles

mole ratio of oxygen gas to ethane = 2.4 : 1

Therefore, oxygen is the limiting reactant

0.14375 moles of oxygen will react with 0.06 moles of ethane to produce 4/5 * 0.14375 moles of CO₂ = 0.115 moles of CO₂

molar mass of CO₂ = 44 g/mol

mass of CO₂ produced = 0.1725 * 44

mass of CO₂ produced = 5.06 g of CO₂

16.1 g of bromine are mixed with 8.42 g of chlorine to give an actual

yield of 21.1 g of bromine monochloride.

Answers

The question is complete, the complete question is;

16.1g of bromine are mixed with 8.42g of chlorite to give an actual yield of 21.1g of bromine monochloride.

Answer:

91 %

Explanation:

Br2 + Cl2 ------>2BrCl

Number of moles of Chlorine = 8.42/71 = 0.119 moles

If 1 mole of Cl2 yields 2 moles of BrCl

0.119 moles of Cl2 will yield 0.119 moles * 2/1 = 0.238 moles of BrCl

Number of moles of Br2 reacted = 16.1/160 = 0.1 moles

If 1 mole of Br2 yielded 2 moles of BrCl

0.1 moles of Br2 yields 0.1 * 2/1 = 0.2 moles of BrCl

Bromine is the limiting reactant.

Mass of BrCl produced = 0.2 moles * 115.357 g/mol = 23.07 g

Theoretical yield = 23.07 g

Actual yield = 21.1 g

Percentage yield = Actual yield/Theoretical yield * 100

= 21.1/23.07 * 100 = 91 %

In an experiment, the theoretical yield of lead sulfate for this reaction was 2.85 g.
In the experiment only 2.53 g of lead sulfate is obtained.
Calculate the percentage yield of lead sulfate in this experiment. * IT

Answers

Answer:

88%.

Explanation:

The percentage yield of lead sulfate in this experiment is 88% if 2.53 is divided by 2.85 and multiply by 100. The percentage yield can be calculated when the experimental yield is divided by theoretical yield and then multiply by 100. The percentage yield tells us about the actual yield that is gained in the end of experiment which is lower than theoretical yield.

A flask is filled with 50.0 ml of 0.15 M HCl acid. Exactly 0.054 grams of CaCo3 are placed in the acid,

neutralizing some of it. How many moles of NaOH must be added in a titration that neutralizes the rest

of the acid?

Answers

Answer:

See explanation

Explanation:

2HCl(aq) + CaCO3(aq) ------->CaCl2(aq) + CO2(g) + H2O(l)

Number of moles of acid present = 50/1000 * 0.15 = 0.0075 moles

Number of moles of calcium carbonate = 0.054g/100 g/mol = 0.00054 moles

2 moles of HCl reacts with 1 mole of calcium carbonate

x moles of HCl reacts with 0.00054 moles of calcium carbonate

x = 2 * 0.00054/1

x = 0.00108 moles of HCl

Amount of acid left = 0.0075 moles - 0.0075 moles = 0.00642 moles

Reaction of HCl and NaOH

HCl(aq) + NaOH(aq) ------> NaCl(aq) + H2O(l)

Since the reaction is in the mole ratio of 1:1

0.00642 moles of HCl is neutralized by 0.00642 moles of NaOH

Answers

The neon atom, a noble gas, has a completely filled valence shell with an octet of electrons. It cannot become an anion by accepting another electron.
Neon has a very high ionization energy of 2080 kJ/mole, and in this respect it is second only to helium. Hence, forming a cation by losing an electron is an extremely difficult task for it.
