Question

Relative mass of proton with respect to hydrogen atom

Answer 1

The absolute mass of hydrogen is 1u. The standard atomic mass is approximately 1.0079u due to the occurrence of isotopes. We consider this as 1u. The hydrogen atom (protium) contains one proton in the nucleus. Hence, all the mass of the H atom is due to the presence of this proton. Hence, we may say that the relative mass of the proton with respect to hydrogen atom is 1. However, considering the average atomic mass as 1.0079u, the relative mass of the proton would be 1/1.0079 = 0.99216.

Answer 2

Answer:

1

Explanation:

The hydrogen atom (protium) contains one proton in the nucleus. Hence, all the mass of the H atom is due to the presence of this proton. Hence, we may say that the relative mass of the proton with respect to hydrogen atom is 1.
