Answer:<\/strong> The atomic mass of hydrogen is approximately 1.008 atomic mass units (amu).<\/p>\n\n\n\n

Atomic mass is the weighted average mass of an atom of an element, considering the relative abundances of its isotopes. It is expressed in atomic mass units (amu), where 1 amu = 1\/12th the mass of a carbon-12 atom.<\/p>\n\n\n\n

Calculation of Atomic Mass of Hydrogen<\/strong><\/p>\n\n\n\n

The atomic mass of hydrogen is calculated by considering the abundance of its isotopes and their respective masses. Here\u2019s how it works:<\/p>\n\n\n\n

Hydrogen has three isotopes:<\/strong><\/p>\n\n\n\n

Protium (\u00b9H): Mass =<\/strong> 1.0078 amu, Abundance \u2248 99.98%<\/p>\n\n\n\n

Deuterium (\u00b2H): Mass =<\/strong> 2.014 amu, Abundance \u2248 0.02%<\/p>\n\n\n\n

Tritium (\u00b3H): Mass =<\/strong> 3.016 amu, Abundance \u2248 Trace amounts (radioactive)<\/p>\n\n\n\n

To find the atomic mass:<\/p>\n\n\n\n

i.e., (1.0078 \u00d7 0.9998) + (2.014 \u00d7 0.0002) + (3.016 \u00d7 trace)<\/p>\n\n\n\n

= 1.008 amu (approx.)<\/p>\n\n\n\n
