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) to 4CO_(2) + 5H_(2)O`
For 58g of `C_(4)H_(10)` 208 g `O_(2)` Is required then for 5 kg of `C_(4)H_(10) O_(2) = (5 xx 208)/(58) = 17.9` kg
