The energy of one mole of photon having ...

The energy of one mole of photon having frequency `4 xx 10^(14)` Hz is

A

`129 kj mol^(-1)`

B

`159 kj mol^(-1)`

C

`145 kj mol^(-1)`

D

`212 kj mol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
E=hv
`=6.626xx10^(-34)xx4xx10^(14)`
`=2.6504 xx10^(-19) j`
for 1 mole photon
`E=2.6504 xx10^(-19) xx6.022 xx10^(23)`
`=159.6 = 159 kj mol^(-1)`
