Question

molar mass of a covalent compound
1 h 1.01
16 s 32.07
what is the molar mass of the covalent compound h2s?
h2s = ? $\frac{g}{mol}$

Explanation:

Step1: Identify molar - mass of H and S

The molar mass of H is 1.01 g/mol and of S is 32.07 g/mol.

Step2: Calculate molar mass of H₂S

For H₂S, there are 2 H atoms and 1 S atom. Molar mass of H₂S = 2×(molar mass of H)+(molar mass of S).
$2\times1.01 + 32.07=2.02 + 32.07 = 34.09$ g/mol

Answer:

34.09 g/mol
