Chapter U4.92, Problem 1E

Interpretation Introduction

Interpretation:

The importance of grams to mole conversion to during a chemical reaction 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:

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

The conversion of grams to moles is necessary because the calculations using moles becomes easy and also the mass of atoms and molecules is so small to count thus, conversion of grams using molar mass to moles makes the calculation required for finding the relative amount of reactant needed and product formed easy.
