20 ml of a gaseous hydrocarbon requires 100 ml of O_2 for
complete combustion and produces 60 ml of CO_2 gas. Determine the
molecular formula of the hydrocarbon.
Show answer and solution
Let the molecular formula of the hydrocarbon is
[IMAGE] From ques. Vol. of CO_2 formed = 60 ml
20 x=60
x=3
vol. of O_2 used = 100 ml
Hence the hydrocarbon is [IMAGE]
[IMAGE] From ques. Vol. of CO_2 formed = 60 ml
