See below:

Explanation:

I assume you mean percentage by mass of the entire compound.

The molar mass of $N a H C O_{3}$ $NaHCO_3$ is $\approx 84 g m o l^{- 1}$ $approx 84 gmol^-1$ and the molar mass of Hydrogen is $\approx 1.01 g m o l^{- 1}$ $approx 1.01 gmol^-1$ , so:

$\frac{1.01}{84} \times 100 \approx 1.2 %$ $1.01/84 times 100 approx 1.2 %$

So Hydrogen is $1.2 %$ $1.2%$ of the entire compound, by mass.
