USE STOICHIOMETRY TO SOLVE
1. What is the molarity of a solution of sodium hydroxide if 32.9 mL is neutralized by 13.4 mL of a 0.198 M phosphoric acid? Round 3 decimal places.

2. Calculate the mass of the solid precipitate formed when 1.32 L of 0.060 M BaCl2 is mixed with 3.73 L of 0.087 M Na2SO4. Round 1 decimal places.

The next 3 questions are solution review (Molarity, dilution, and % Concentration) questions.

3. What mass of calcium bromide is needed to prepare 3.78 mL of a 1.70 M solution? Round 2 decimal places.

4. How many mL of a 11 M hydrochloric acid do you need to make 500 mL of 1.9 M HCl solution? Round to the nearest whole number.

5. A saline IV bag, is prepared for a patient at the hospital. What mass of NaCl would need to be dissolved in the 985 mL of solution to make the 1.13% (m/v) IV? Round 2 decimal places.
