1) You are asked to make 10 miles of iron (Fe) from iron oxide (Fe2O3) and excess carbon monoxide (CO). Fe2O3 (s) + 3CO (g) - > 2Fe (l) + 3O2 (g). How many moles of iron oxide must you use.

A) 3 moles

B) 2 moles

C) 10 moles

D) 5 moles

2) 2C4H10 + 13O2-> 8CO2 + 10H2O. If I want to produce 50g of H2O using the above combustion reaction, how many mol of C4H10 should I use?

A) 0.55 mol C4H10

B) 10 mol C4H10

C) 2.77 mol C4H10

D) 3.79 mol C4H10

For both of them, used the balanced equation and it's mole ratio to convert whatever you need to into moles. See the attacked work.

1) D 5 mols

2) A 0.55 mols
