Stoichiometry Review Assignment Example 1: Calculate the mass of a magnesium, Mg, atoms in grams. Example 2: Calculate the number of atoms in one-millionth of a gram of magnesium, Mg. Example 3: How many atoms are in 1.67 moles of magnesium? Example 4: How many moles of magnesium are in 73.4 grams of magnesium? Example 7: Calculate the number of propane, C 3 H 8 molecules, in 74.6 grams of propane. Example 8: What is the mass of 10.0 billion molecules of propane? Example 9: How many moles, molecules, and oxygen atoms are contained in 60-g sample of ozone O 3 ? Example 13: What mass of phosphorous is contained in 45.3 grams of (NH 4 ) 3 PO 4 ? Example 14: What mass of ammonium phosphate would contain 15.0 g of nitrogen? Example 15: What mass of propane, C 3 H 8 , contains the same mass of carbon as is contained in 1.35 grams of barium carbonate, BaCO 3 ?
