Answer:
Mass of solvent is 1127.3 g
Explanation:
NaOCl → 3.62%
This percent means, that in 100 g of bleach solution, there are 3.62 g of NaOCl. So let's make a rule of three:
100 g of bleach solution have 3.62 g
1169.6 g of bleach solution may have (1169.6 . 3.62) /100 = 42.3 g
42.3 g is the mass of NaOCl in the solution
Mass of solution = Mass of solvent + Mass of solute
1169.6 g = Mass of solvent + 42.3 g
1169.6 g - 42.3 g = Mass of solvent → 1127.3 g
