What volume of carbon dioxide is produced by burning 90 g of ethane in air?
--- End quote ---
C2H6 + 3.5O2 --------> 2CO2 + 3H2O
After you form the above equation do this:
90g / (24+6) = 3 moles of ethane
2*3 moles = 6 moles of CO2 (using the molar ratio)
6*24 = 144 dm3

I balanced it correctly on the rough paper I had; I was in a rush so I missed it out whilst typing :-[
I removed the quote from your post so Nidzzz doesnt get confused, is that alright ?
