Calculate the molecular mass of the following compounds Hydrogen sulphide, $\left({\mathrm{H}}_2\mathrm{S}\right)$

Given Atomic masses: S = 32u, H = 1u

Step 1: Calculating the molecular mass

Molecular mass is equal to the sum of atomic masses of all the atoms present in one molecule of a substance.

Step 2: Given data

Atomic masses: S = 32u, H = 1u

Step 3: Finding the molecular mass for the given data

The molecular mass of $\left({\mathrm{H}}_2\mathrm{S}\right)$ = $\left(2\times 1\right)+\left(1\times 32\right)$

Hence, the molecular mass of $\left({\mathrm{H}}_2\mathrm{S}\right)$ = $34$u
