Chromium metal will react with oxygen gas to produce chromium(III) oxide (molar mass = 152.0 g/mol), according to the equation below.
4 Cr (s) + 3 O2 (g) --> 2 Cr2O3 (s)
a) If 1.48 moles of Cr is reacted with 1.03 moles of O2, which reactant is limiting and which reactant is in excess?
b) What is the theoretical yield (in grams) of Cr2O3?
