Homework Answers
Step 1: Explanation
Mass percent is equal to the mass of the substance divided by the total mass times 100 percent.
Simply, Mass = Total mass of solution × (given percent /100 )
Step 2: Calculation
(A) Mass of KCl = 21.7 g × 1.12/100 = 0.243 g
(B) Mass of KCl = 23.2 kg × 20.2/100 = 4.69 kg
(C) Mass of KCl = 38 mg × 13/100 = 4.9 mg
