What is the volume (in litres) of oxygen atSTP required for complete combustion of 32g of `CH_4` ? (Molecular weight of `CH_4`.)

A

44.8

B

89.6

C

22.4

D

179.2

Text Solution

Verified by Experts

The correct Answer is:
b
` underset ((16g))(CH_4+2O_2 )to underset((2xx22.4 L))(CO_22H_2O`
Volume of `O_2` required for 16 g 0f `CH_4=2xx22.4 L`
Volume `O_2` required for 32 g of `CH_4=(2xx22.4xx32)/16`
`=89.9 L`
