Question

How many moles of carbon dioxide are produced by the combustion of 4 moles of C12H26 with 41.6

moles of O₂ (answer in moles)?

Answer 1

Answer: 24 moles CO2

Step-by-step explanation:

1) write and balance the equation

2 C12H26 + 25 O2 --> 12 CO2 + 26 H2O

2) solve for limiting reactant which is 4 moles C12H26

3) stoichiometry using Limiting reactant

4 moles C12H26 x ( 12 moles Co2/2 moles C12 H26) = 24 moles CO2
