| 1. | An experiment requires 2.00 L of 0.200 M hydrochloric acid (HCl) solution. What volume of concentrated hydrochloric acid, containing 11.9 M hydrogen chloride, is needed? |
| 2. | A chemist adds water to 120 mL of a 6.0 M solution of NaOH until the final volume is 2.0 L. What is the molarity of the resulting solution? |
| 3. | What concentration results when 150 mL of a 0.36 M solution of magnesium sulfate, MgSO4, are added to enough water to give a final solution volume of 750 mL? |
| 4. | What concentration results when 150 mL of a 0.36 M solution of magnesium sulfate, MgSO4, are added to 750 mL of water? |
