<span>the balanced chemical equation for the reaction is as follows;
 C</span>₃H₈ + 5O₂ ---> 3CO₂ + 4H₂<span>O
                   
stoichiometry of </span> C₃H₈ to O₂ is 1:5
   
number of moles of  C₃H₈ reacted - 0.025 g / 44.1 g/mol = 0.000567 mol according to molar ratio of 1:5
number of O₂ moles required are 5 times the amount of  C₃H₈ moles reacted therefore number of O₂ moles required - 0.000567 x 5 = 0.00284 mol .
mass of O₂ required - 0.00284 mol x 32.00 g/mol = 0.091 mol .
 answer is 0.091 mol

Calculating molarity using solute moles A chemist prepares a solution of sodium chloride (NaCl) by measuring out 6.89 mol of sod
hram777 [196]

Answer: Concentration of the chemist's sodium chloride solution is 34.4 mol/L.

Explanation:

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

Molarity=\frac{n\times 1000}{V_s}

where,

n= moles of solute

V_s = volume of solution in ml

Given : moles of NaCl = 6.89

volume of solution = 200 ml

Putting in the values we get:

Molarity=\frac{6.89\times 1000}{200}=34.4mol/L

Thus the concentration of the chemist's sodium chloride solution is 34.4 mol/L.
