Question

What is the percent by mass of solute if 14.15 g of NaI is mixed with 75.55 g of water?

Answer 1

Answer:

15.77 %

Explanation:

Weight of solute and solvent  14.15+75.55=89.70

Since 89.70 gm of total weight containing 14.15 gm solute

Hence what is percent of solute if total weight is 100 gm

100⋅  14.15/89.70=15.77

Hence answer is 15.77 %

Answer 2

sum of solute and solvent

14.5 + 75.55 = 89.70gm

percent of solute if total weight is 100 gm

100* 14.15 / 89.70

answer is 15.77 %
