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

Answer 1

15.77 %

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 %
