Question

The most abundant elements by mass in the body of a healthy human adult are oxygen 61.4%, carbon 22.9%, Hydrogen 10.0%, Nitrogen 2.6%. The weight which a 75 kg person would gain if all 1H atoms are replaced by 2H atoms is

Answer 1

Answer:

Total weight of person 75kg

mass due 1H =75x10/100= 7.5kg

1H atoms are replaced by 2H atoms,

Mass due to 2H = (7.5x 2)kg

Mass gain by person

7.5kg

THANKS

Answer 2

Explanation:

If it is replaced by then mass will be doubled so now hydrogen mass = 15 kg So, mass of person will be increased by 7.5 kg.
