For the combustion of ethane,beginning with 0.27 mole of CH3 CH3.
How many moles of CO2 are obtained when the CH3 CH3 is completely combusted?

The balanced chemical equation for the combustion of ethane is:

2CH3CH3 + 7O2 → 4CO2 + 6H2O

This means that for every 2 moles of CH3CH3 combusted, 4 moles of CO2 are produced.

Using this ratio, we can calculate how many moles of CO2 are obtained from 0.27 mole of CH3CH3:

(0.27 mol CH3CH3) x (4 mol CO2 / 2 mol CH3CH3) = 0.54 mol CO2

Therefore, 0.54 moles of CO2 are obtained when 0.27 mole of CH3CH3 is completely combusted.
