2C2H6 + 7O2 -> 4CO2 + 6H2O

A) what volume of oxygen would be required to burn 1dm3 of ehane?
B) what volume of carbon dioxide would be produced?

Been stuck on this for hours cant do it anymore

2 moles of Ethane react with 7 moles of Oxygen
2:7 = 1:x
x = 3.5dm3

B) what volume of carbon dioxide would be produced
2 moles of Ethane produces 4 moles of Carbon Dioxide
2:4 = 1:x
x = 2 dm3
