1) How many molecules of hydrogen gas can be produced when 2.79 g of sodium metal is dropped in a beaker of water? (hint: the other product is sodium hydroxide)

2) 5.96 grams of sodium phosphate is combined with 6.88 g of iron (III) nitrate. Assuming this reaction goes to completion, identify the precipitate and its mass that will be produced.

3) 3.167 g of lead (II) nitrate is mixed with 1.895 g of potassium iodide. What is the maximum mass of lead (II) iodide that can be produced in this reaction?
