State the number of hydrogen atoms in $1\,g$ of hydrogen.
(N/A) The molar mass of hydrogen $(H)$ is $1\,g/mol$.
Given mass of hydrogen $= 1\,g$.
Number of moles $= \frac{\text{Given mass}}{\text{Molar mass}} = \frac{1\,g}{1\,g/mol} = 1\,mol$.
Since $1\,mol$ of any substance contains $6.022 \times 10^{23}$ particles (Avogadro's number),the number of hydrogen atoms in $1\,g$ of hydrogen is $6.022 \times 10^{23}$ atoms.
