If a body of a fish contains 1.2 g hydrogen in its total body mass, if all the hydrogen is replaced with deuterium then the increase in body weight of the fish will be

A

1.2 g

B

2.4 g

C

3.6 g

D

`sqrt(4.8)` g

Text Solution

Verified by Experts

The correct Answer is:
A
mass of deuterium = 2 `xx` mass of protium If all the 1.2 g hydrogen is replaced with deuterium, the weight will become 2.4g. Hence the increase in body weight is (2.4 -1.2 = 1.2 g)
