Calculate the largest amount of CO2 that could be produced.

Question

Methane (CH4) gas and oxygen (O2) gas react to form carbon dioxide (CO2) gas and water (H2O) vapor. 

Suppose you have 9.0 mol of (CH4) and 3.0 mol of (O2) in a reactor.

Calculate the largest amount of CO2 that could be produced.

Round your answer to the nearest 0.1 mol

.

Answer 1

Well the equation is

CH4 + 2 O2 = CO2 + 2 H20

So with 9 moles of CH4 and 3 moles of O2, all the O2 will react giving 1.5 moles of CO2 (2 O2 forms 1 CO2). Only 1.5 moles of CH4 will react leaving 7.5 moles unreacted .

So 1.5 moles of CO2 produced.
