1. If 62.00 g of magnesium sulfate is dissolved in 300.0 ml of aqueous solution, find the molarity.

2. How much calcium nitrate would I need to measure out to make 400.0 ml of a 0.150 M solution?

3. How much sodium carbonate is needed to make up 500.0 ml of a 0.200 M solution?

4. How much of a 3.000 M solution of NaOH is needed to make 200.0 ml of a 0.100 M solution?

What measurement and mixing procedures must be followed?

5. A chemist needs 200.0 ml of a 0.100 M solution of H₂SO₄. She has some 6.000 M H₂SO₄ on hand. How should she proceed?

6. A chemist needs 450.0 ml of a 0.200 M solution of potassium sulfate. How much potassium sulfate is needed, and what propcedure should he follow?

7. A chemist dilutes 15.0 ml of 6.00 M nitric acid to a final volume of 200.0 ml. Find the resulting molarity.
