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
Answer:
The mass of solvent is 1127.26 grams
Explanation:
Step 1: Data given
Mass of the solution = 1169.6 grams
mass % of NaOCL = 3.62 %
Step 2: Calculate mass of solute
Percent by mass of NaOCl = (mass NaOCl / mass of bleach solution) *100%
3.62 = (mass of NaOCl / 1169.6 grams )* 100%
0.0362 = mass of NaOCl / 1169.6 grams
Mass of NaOCl = 0.0362 * 1169.6 grams
Mass of NaOCl = 42.34 grams
Step 3: Calculate mass of solvent
1169.6 grams - 42.34 grams = 1127.26 grams
This should be 96.38 %
(1127.26/1169.6) * 100 % = 96.38 %
The mass of solvent is 1127.26 grams
