Question

I'm looking for some help on a chemistry question I have:

a) What is the percent yield of iron if the reaction of 63.1 g of iron(III) oxide produces 14.9 g of iron?

b) What is the percent yield of carbon dioxide if the reaction of 75.5 g of carbon monoxide produces 84.4 g of carbon dioxide?

c) Calculate the mass of CO2 that can be produced if the reaction of 41.4 g of pentane and sufficient oxygen has a 57.0 % yield.

d) What is the theoretical yield of aluminum oxide if 3.80 mol of aluminum metal is exposed to 3.15 mol of oxygen?

Thanks in advance!
