Question

Calculate the mass of proton in kg from atomic mass of hydrogen which is 1.008 u​

Answer 1

Explanation:

Mass of proton = (Mass of hydrogen - mass of electron) for 1 atom

= 1.008 u - 0.00005 u

= 1.00795 u

1 u = 1.66053 × 10-27 kg

Mass of proton = 1.66053 ×10-27×1.00795 = 1.6737 ×10-27 kg.
