Chapter 10.2, Problem 23SSC

Interpretation Introduction

Interpretation:

The conversion factors used to convert between mass and moles of any element needs to be explained.

Concept introduction:

Molar mass of any compound & defined as the sum of the sum of masses of all the atoms present in the compound. Molar mass is given in $\text{g/mol}$. As the molar mass is given for one mole, one can convert moles to mass by multiplying the molar mass with the given number of moles.

Explanation of Solution

Molar mass of a compound is defined for $1$ mole. So if there are n number of moles, then one can find the mass of n moles by multiplying the molar mass by n. Similarly if the mass of any compound is given, one can find the number of moles present by dividing the molar mass by the given mass.

For example, fluorine has molar mass of $18.99\text{ g/mol}$ and the conversion factors for fluorine include $18.99\text{ grams}$
