1 g of hydrogen is converted into 0.993 ...

`1 g` of hydrogen is converted into `0.993 g` of helium in a thermonuclear reaction. The energy released is.

A

`63xx10^(7)J`

B

`36xx10^(10)J`

C

`63xx10^(14)J`

D

`63xx10^(20)J`

Text Solution

Verified by Experts

The correct Answer is:
B
Mass defect, `Deltam=1-0.993=0.007g`
`therefore` Energy released, `E=(Deltam)c^(2)`
`=(0.007xx10^(-3))xx(3xx10^(8))^(2)=63xx10^(10)J`
