Chapter U4.25, Problem 1TAI

Interpretation Introduction

Interpretation:

The conversion of grams to moles and determination of mass using moles should be predicted.

Concept Introduction:

The amount of the substance that contains the same number of particles or atoms or molecules is termed as mole.

Explanation of Solution

Mole can be expressed as the ratio of given mass and molar mass of the compound. The expression for mole is represented as follows:

  $\text{Mole}=\frac{\text{Given}\text{mass}}{\text{Molar}\text{mass}}$

Thus, the mass using moles would be calculated as follows:

  $\begin{array}{c}\text{Moles}=\frac{\text{Given}\text{mass}}{\text{Molar}\text{mass}}\\ \text{Given}\text{mass}=\text{Moles}\times \text{Molar}\text{mass}\end{array}$
