How many moles of C6H12O2 are needed to get 12 moles of CO2

2 moles of C6H12O2

Explanation:

First, we'll begin by writing a balanced equation for the reaction showing how CO2 is produce from C6H12O2.

This is illustrated below:

C6H12O2 + 8O2 —> 6CO2 + 6H2O

From the balanced equation above,

1 mole of C6H12O2 produced 6 moles of CO2.

Therefore, Xmol of C6H12O2 will produce 12 moles of CO2 i.e

Xmol of C6H12O2 = 12/6 = 2 moles

Therefore, 2 moles of C6H12O2 are needed to produce 12 moles of CO2
