(a) Interpretation: The number of molecules of substance should be calculated. Concept Introduction: Number of moles is related to mass and molar mass as follows: n = m M Here, m is mass and M is molar mass. According to Avogadro’s law, 1 mole of a substance contains 6.023 × 10 23 atoms. This is known as Avogadro’s number and denoted by symbol N A . Thus, number of molecules can be calculated from number of moles using the following conversion factor: ( 6.023 × 10 23 molecules 1 mol ) .

Solutions

Chapter 8, Problem 40QAP
Interpretation Introduction

(a)

Interpretation:

The number of molecules of substance should be calculated.

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 contains 6.023×1023 atoms. This is known as Avogadro’s number and denoted by symbol NA.

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

(6.023×1023 molecules1 mol).
