Molarity Practice Problems Note: Below are a few problems for you to practice with. Take time to write out the setups rather than just punching numbers into your calculator.

1. Seawater contains roughly 28.0 g of NaCl per liter. What is the molarity of sodium

chloride in seawater?

2. What is the molarity of 245.0 g of H 2 SO 4 dissolved in 250 mL of solution?

3. What is the molarity of 5.30 g of Na 2 CO 3 dissolved in 400.0 mL solution?

4. What is the molarity of 5.00 g of NaOH in 750.0 mL of solution?

5. How many moles of Na 2 CO 3 are there in 10.0 L of 2.0 M solution?

6. How many moles of Na2CO3 are in 10.0 mL of a 2.0 M solution?

7. How many moles of NaCl are contained in 100.0 mL of a 0.20 M solution?

8. What mass (in grams) of NaCl would be contained in problem 7?

9. What mass (in grams) of H2SO4 would be needed to make 750.0 mL of 2.00 M

solution?

10. What volume (in mL) of 18.0 M H2SO4 is needed to contain 2.45 g H2SO4?
