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

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.
