1.	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) \(\sqrt{4.8}\, g\)
Answer» (a) 1.2 g Mass of deuterium = 2 × (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).

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) \(\sqrt{4.8}\, g\)

Answer»

(a) 1.2 g

Mass of deuterium = 2 × (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).
