Answer to Question #90047 in General Chemistry for Bob

Question

What is the percentage of chlorine in sodium chloride

Answer 1

By mol, each NaCl has 1 mol Na and 1 mol Cl, a total of 2 mol. Therefore Cl is 1/2 = 50%.

By mass, Na’s molar mass is 22.990 while Cl’s molar mass is 35.453, a sum of 58.443/mol. 35.453/58.443 = 0.6066 = 60.66%.
