Molarity Problems Worksheet

M = _n_

- n= # moles

- V must be in liters (change if necessary)

- Use M or mol/L as unit for molarity

1. What is the molarity of a 0.30 liter solution containing 0.50 moles of NaCl?

2. Calculate the molarity of 0.289 moles of FeCl

dissolved in 120 ml of solution?

3. If a 0.075 liter solution contains 0.0877 moles of CuCO

, what is the molarity?

4. How many moles of NaCl are present in 600. ml a 1.55 M NaCl solution?

5. How many moles of H

are present in 1.63 liters of a 0.954 M solution?

6. How many liters of solution are needed to make a 1.66 M solution containing 2.11 moles of

KMnO
