The _________ of a substance is the mass (in grams) of 1 mole of the substance.

Interpretation Introduction

Interpretation:

The term for mass in (grams) of 1 mole of a substance should be determined.

Concept Introduction:

Number of moles is related to mass and molar mass as follows:

n=mM

Here, m is mass and M is molar mass.

According to Avogadro’s law, 1 mole of a substance contains6.023×1023 atoms. This is known as Avogadro’s number and denoted by symbolNA.

Thus, number of molecules can be calculated from number of moles using the following conversion factor:

(6.023×1023 molecules1 mol).

Explanation of Solution

The unit for molar mass of a substance is g/mol that is mass in grams of a substance in 1 mol of that substance.

For example: Molar mass of calcium is 40...
