Molarity Problems
1. What is the molarity of a
solution that was prepared by dissolving 14.2 g of NaNO3 (molar mass = 85.0
g/mol) in enough water to make 350 mL of solution?
2. What is the molarity of a
solution that was prepared by dissolving 82.0 g of CaCl2 (molar mass = 111.1
g/mol) in enough water to make 812 mL of solution?
3. What is the molarity of a
solution that contains 5.5 g of HCl (molar mass = 36.5 g/mol) dissolved in
enough water to make 250 mL of solution?
4. How many grams of NaBr (molar
mass = 102.9 g/mol) would be needed to prepare 700ml of 0.230 M NaBr solution?
