Suppose, the volume of propane =V L undersetv∴ C 3 H 8( g )+5 O 2( g ) longrightarrow underset5v3 CO 2( g )+ underset3v4 H 2 O (ℓ) C 4 H 10( g )+(13/2) O 2( g ) longrightarrow 4 CO 2( g )+5 H 2 O (ℓ) (3-v) (13/2)(3-v) 4(3-v) Total volume of CO 2 produced =10 L; 3 K+4(3-F)=11 ; ∴ V=1 ∴ Volume of butane =(3-1)=2 L Thus, the ratio of volume of butane to propane. =2: 1
