2c2h6+7o2=4co2+6h2o in the combustion of ethane how many moles of co2 can be produced from 1.00 mole of C2H6

Question

I have no idea how to do that!

Answer 1

According to the reaction:
2 mol of C2H6 produce 4 mol of CO2
5.70 mol of C2H6 ‒ x moles of CO2

 

So, the number of moles of CO2 produced by combustion of 5.70 mol of ethane equals:

 

x=    5.70 x 4

       -------------        =11.4 mol

              2

Answer: n(CO2) = 11.4 mol.
