The most abundant elements by mas in the body of a healthy human adult are Oxygen `(61.4%)`, Carbon `(22.9%)`. Hydrogen `(10.0)%)`, and Nitrogen `(2.6%)`. The weight which a `75 kg` person would gain if all `.^(1)H` atoms are replaced by `.^(2)H` atoms is

A

37.5 kg

B

7.5 kg

C

10 kg

D

15 kg

Text Solution

Verified by Experts

The correct Answer is:
B
75 kg person contain 10% hydrogen i.e. 7.5 kg Hydrogen.
If all H atom are replaced by `.^(2)H`, the weight of Hydrogen become twice i.e., it increased by 7.5 kg
