Unit 10: Stoichiometry Review – Pre-AP (1) How many moles are in 85.2 grams of iron (II) oxide? (2) How many atoms are in 0.6144 mol of copper? (3) Calculate the number of molecules in 3.5 grams of CO 2 . (4) How many grams are in 1.20 x 10 26 atoms of aluminum metal? (5) What is STP? What volume does one mole of any gas occupy at STP? (6) What mass of CO would occupy a volume of 35.6 L at STP? (7) How many atoms of argon are in 58.0 L of argon gas at STP? (8) The density of a gaseous compound of carbon and oxygen is 1.964 g/L at STP. Determine the molar mass of the compound. Is the compound carbon dioxide or carbon monoxide? (9) The density of a gas at STP is 1.254 g/L. What is the molar mass of the gas? (10) What is the density of NO at STP? (11) Calculate the percentage composition of copper inCu 2 S. (12) Distinguish between empirical formulas and molecular formulas. Give an example of each. (13) Determine the empirical formula for a compound which is 67.6% Hg, 10.8% S and 21.6% O.
