3. What is solubility?

4. How do you calculate molarity?

5. You have 3.50 L of solution that contains 90.0 g of sodium chloride. What is the molarity of that solution?

6. You have 80 mL of a 0.5 M HCl solution. How many moles of HCl does this solution contain?

7. How many grams does this represent?

8. How many grams hydrogen sulfate would be required to react with 755 mL of 2.50 M aluminum hydroxide, if the products are aluminum sulfate and water?

9. What volume of 0.25 M HCl would be required to react completely with 0.756 grams of sodium hydroxide?

10. What volume of 12 M HCl would be required to completely react with 250. mL of a 2.48 M HCl solution?

Use the solubility rules, to decide whether the following are soluble or not.
