Calculate the energy which can be obtained from 1 kg of `H_(2)O` through the fusion reaction `""_(1) ^(2) H + ""_(1) ^(2) H to ""_(1) ^(2) H + p.` Assume `1.5x x 10^(2)%` of the water contains deuterium. The whole deuterium is consumed in the fusion reaction.

A

`2828J`

B

`2820 xx10 ^(4) J`

C

`2820 xx 10 ^(6) J`

D

`2820 xx 10 ^(8) J`

`D _(2) O = 1 xx1. 5 xx 10 ^(-4) kg = 0. 15 g.`
Number of `""_(1) ^(2) H = (0. 15 xx 6. - 23 xx 10 ^(23))/(20) = 4.5 xx 10 ^(21)`
`Q = ( 2 xx 2. 0 14102 - 3. 01 6049 - 1. 008) 931. 5 xx 4.5 xx 10 ^(21) xx 1. 6 xx 10 ^(-13)J = 2820xx 10 ^(6) J`
