Problems 1 - 3 are the first calculation type - molarity is asked for in the problem.
Problems 4 - 6 are the second calculation type - molarity is given in the problem.

1. Calculate the molarity of a solution that contains 0.37 g CaCl₂ in 340 milliliters of solution.    

    

2. Calculate the M of 200 cm³ of a solution containing 50 g NaOH.    

    

3. What is the solution concentration when 250 grams of iron (III) hydroxide are dissolved in enough distilled water to make 2.0 liters of solution?    

    

4. How much base is needed to make 50 cm³ of 0.2 M Al(OH)₃?    

    

5. How much calcium sulfate is needed to make 100 cm³ of 0.25 M CaSO₄?    

    

6. How many grams of HCl are in 100 ml of a 0.5 M hydrochloric acid solution?
