Interpretation Introduction

Interpretation:

The molecular weights for the given compounds and the amount of ${\text{PH}}_{\text{3}}$ that contain the same number of molecules as $\text{6}\text{.41}\text{g}$ of ${\text{SO}}_2$ is to be calculated.

Concept introduction:

Molar mass is the sum of the atomic masses of all the atoms present in the chemical formula of any compound. One mole of substance contains $6.02\times {10}^{23}$ atoms or molecules. This number is known as the Avogadro number.
