Question

Mass of one atom of x is 6.642*10-23 g. Find its atomic mass

Answer 1

Unified atomic mass unit = $1.66 \times 10^{-27} \, \mathrm{kg} = 1.66 \times 10^{-24} \, \mathrm{g}$

Atomic mass = Mass of one atom / Unified atomic mass unit = $6.642 \times 10^{-23} \, \mathrm{g} / 1.66 \times 10^{-24} \, \mathrm{g} = 40$
