Question

What is the weight of $1$atom of hydrogen?

Answer 1

Step 1. Given information

$1$ atom of hydrogen

Step 2:

Atomic mass of hydrogen = $1\mathrm{g}$

So, weight of one mole of hydrogen = $1\mathrm{g}$

No. of atoms in one mole = $6.022\times {10}^{23}$

Step 3:

Weight of $6.022\times {10}^{23}$ atoms of hydrogen = $1\mathrm{g}$

Therefore, weight of $1\text{atom}$ of hydrogen is $\frac{1\text{g}}{6.022\times {10}^{23}}=1.66\times {10}^{-24}\text{g}$

The weight of atom of hydrogen is $1.66\times {10}^{-24}\text{g}$.
