Chromium and oxygen combine to form chromium (III) oxide.4Cr(s)+3O2(g)→2Cr2O3(s)
How many moles of O2 react with 4.85 mol of Cr?
How many grams of Cr2O3 are produced when 23.6 g of Crreacts?
When 25.0 g of Cr reacts with 7.20 g of O2, how many grams ofCr2O3 can form?
If 72.1 g of Cr and 68.0 g of O2 are mixed, and 87.0 g of Cr2O3is actually obtained, what is the percent yield of Cr2O3 for thereaction?
Express your answer with the appropriate units.
