A certain amount of charge is passed through acidulated water. A total of `504mL` of hydrogen and oxygen were collected at STP. Find the magnitude of charge that is passed during electrolysis in coulombs.

A

`1930C`

B

`965C`

C

`482.5C`

D

`241.2C`

Text Solution

Verified by Experts

The correct Answer is:
b
`1F=1eq `of `O_(2)=(22.4)/(4)=5.6L` of `O_(2)`
`1D=1eq` of `H_(2)=(22.4)/(2)=11.2L` of `H_(2)`
`1F=(5.6+11.2)L=16.8 ` of `O_(2)` and `H_(2)=16800mL`
`168mL (O_(2)+H_(2))=1F=96500C`
`:. 168mL =965C`
