How many moles of CO2 (g) are produced when 1.1 mol C2H6 (g) are consumed?

Write a balanced equation for the combustion of ethane (C2H6). A combustion of a hydrocarbon consumes oxygen and produces water and carbon dioxide:
2C2H6 + 7O2 --> 4CO2 + 6H2O
Obtain the mole ratio by looking at the coefficients: every two moles of C2H6 consumed yields 4 moles CO2.
(1.1 mol C2H6)(4 mol CO2 / 2 mol C2H6) = 2.2 mol CO2

if you mean by consumed combustion in an adequate volume of dioxygen, then :
2 C2H6 + 7 O2 ------> 4 CO2 + 6 H2O
we have : nf(C2H6) = 1.1 - 2 xmax = 0
so xmax = 0.55 mol
and we have : nf(CO2) = 4 xmax = 2.2 mol
