Chapter U4.78, Problem 1TAI

Interpretation Introduction

Interpretation:

The relation between moles and mass needs to be explained.

Concept introduction:

The relation between mass and number of moles is as follows:

  $n=\frac{m}{M}$

Here, m is mass and M is molar mass.

Explanation of Solution

The mass can be calculated from molar mass as follows:

  $m=n\times M$

Thus, moles and mass can be converted to each other easily. Mass of a substance is equal to moles of the substance multiplied by its molar mass.
