How many coulomb are required to liberate 1.12`m^(3)` of hydrogen at S.T.P. during electrolysis?

A

965

B

96500

C

9650000

D

96.5

Text Solution

Verified by Experts

The correct Answer is:
C
`1000 dm^3 =1m^3`
`therefore 22.4 dm^3 =22.4 xx 10^(-3) m^3`
`22.4xx10^(-3)m^3 of H_2 -= 2xx96,500 C`
`1.12 m^3 -=96,50,000C`
