1.	Mass of an atom of hydrogen in gram is 1.6736 × 10-24 g. What is the atomic mass of hydrogen in u?
Answer» Given : Mass of an atom of hydrogen in gram is 1.6736 × 10^-24g. To find : Atomic mass of hydrogen in u Calculation : 1.66056 × 10^-24g = 1 u ∴ 1.6736 × 10^-24 g = x x = \(\frac{1.6736\times 10^{-24}g}{1.66056\times 10^{-24}g/u}\) = 1.008u ∴ The atomic mass of hydrogen in u = 1.008 u

Mass of an atom of hydrogen in gram is 1.6736 × 10-24 g. What is the atomic mass of hydrogen in u?

Answer»

Given :

Mass of an atom of hydrogen in gram is 1.6736 × 10^-24g.

To find :

Atomic mass of hydrogen in u

Calculation :

1.66056 × 10^-24g = 1 u

∴ 1.6736 × 10^-24 g = x

x = \(\frac{1.6736\times 10^{-24}g}{1.66056\times 10^{-24}g/u}\)

= 1.008u

∴ The atomic mass of hydrogen in u = 1.008 u
