The mass fraction of the hydrogen atom is 0.9995 u.

Calculation:

We know that mass fraction can be determines as,

Mass fraction = Mass of proton/mass of H atom

Given,

Mass of proton = 1.007276 u

Mass of H atom = 1.007825 u

Put the values in the formula,

Mass fraction = Mass of proton/mass of H atom

Mass fraction = 1.007276/1.007825

                       = 0.9995 u

Hence, the mass fraction of the hydrogen atom is 0.9995 u.
