Question

Calculate the loss in Mass during the change
3Li^7+ 1H¹——>2 2HE⁴+ 17.25 MeV

Answer 1

Answer:

0.0185 u

Explanation:

It can be calculated by the following simple relation

$energy \: evolved = loss \: in \: mass \: (in \: amu) \: \times 931$

the answer would be in mega electron volt (MeV)

THUS

$the \: loss \: in \: mass = \frac{energy \: evolved}{931}$

=> mass = 17.25 / 931 = 0.0185 amu
