Heavy water is found in minute quantities in rain water, on the leaves of Banyan trees, and in the last remain obtain by melting of snow as in himalayas.
The weight precentage fo deuterium in heavy water is

A

0.02

B

0.5

C

0.2

D

0.1

Text Solution

Verified by Experts

The correct Answer is:
C
Molecular weight of `D_2O = 20`
4 grams of D in 20 grams of `D_2O`
Therefore percentage of `D = 4/20 xx 100 = 20`
