Ethane burns in oxygen to form CO2 and H2O according to the equation :
2C2H6+7O2→4CO2+6H2O.
If 1250 cc of oxygen is burnt with 300‌cc of ethane.
Calculate:

Question : 69

Total: 80

the volume of CO2 formed.

Solution:

2C2H6	+	7O2	→	4CO2	+	6H2O
2	:	7	:	4

If 2 vol. of C2H6 forms 4 vol. of CO2 then 300‌cc of C2H6 forms ‌

×300
=600‌cc‌ of ‌CO2
