Expert Answer
The combustion reactions are as;
Let the volume of propane be x lit and volume of butane be 3-x lit.
CO2 formed by combustion of propane is 3x
CO2 formed by combustion of butane is 4(3-x)
We have,
x+y =10 lit
Therefore
3x + 4(3-x) = 10
3x + 12 -4x = 10
x = 2 lit
As x is volume of propane = 2 lit
and volume of butane = (3 - x)
=3-2 = 1 lit
Therefore the composition of mixture is
Propane : Butane is 2:1
