Answer to Question #96055 in General Chemistry for Katie

Question

Propane, C3H8 , reacts with oxygen in the combustion reaction below.

C3H8+5O2→4H2O+3CO2

If 30.0 g of C3H8 reacts with 75.0 g O2, how much of each species will remain after the reaction is complete?

Answer 1

n(C3H8) = 0.682 mol

n(O2) = 2.344 mol

O2 is limited

After reaction:

n(C3H8) = 0.215 mol

m(C3H8) = 9.46 g

n(O2) = 0

m(O2) = 0

n(H2O) = 1.875 mol

n(CO2) = 1.400 mol
