Answer:
525 grams
Explanation:
Assuming the solution to be prepared is 15% by weight calcium chloride, it means 15 grams of calcium chloride will be in 100 mL of solution.
To calculate the amount needed to make 3500 mL solution;
15 g is required to make 100 mL
X g is required to make 3500 mL
X = 15 x 3500/100
= 525 g
Therefore, 525 grams of calcium chloride will be needed to make 15%, 3500 mL of calcium chloride solution.
