If isobutane and n-butane are present in a gas, then how much oxygen should be required for complete combustion of 5 kg of this gas

A

17.9 kg

B

9 kg

C

27 kg

D

1.8 kg

Text Solution

Verified by Experts

The correct Answer is:
A
Isobutane and n-butane `[C_(4)H_(10)]` have same molecular formula, `C_(4)H_(10)+13/2 O_(2) rarr 4 CO_(2)+5 H_(2)O`
For 58 gm of `C_(4)H_(10)` 208 gm `O_(2)` is required then for 5 kg of `C_(4)H_(10)" "O_(2)=(5xx208)/58=17.9 kg`
