Question

what is the molar mass of the covalent compound h₂s? h₂s = ? g/mol

Explanation:

Step1: Calculate the mass of hydrogen

There are 2 hydrogen atoms in \(H_2S\). The molar mass of \(H\) is \(1.01\frac{g}{mol}\). So the mass of \(H\) in \(H_2S\) is \(2\times1.01\frac{g}{mol}\)=$2.02\frac{g}{mol}$

Step2: Calculate the mass of sulfur

There is 1 sulfur atom in \(H_2S\). The molar mass of \(S\) is \(32.07\frac{g}{mol}\)

Step3: Calculate the molar mass of \(H_2S\)

Add the mass of \(H\) and \(S\) together. \(M = 2.02\frac{g}{mol}+32.07\frac{g}{mol}\)

Answer:

\(34.09\frac{g}{mol}\)
