Chapter 8, Problem 105AP

Interpretation Introduction

(a)

Interpretation:

Using the average atomic masses, the number of atoms of the sample should be determined.

160, 000 amu of oxygen

Concept Introduction:

Atomic mass unit measures mass in an atomic scale, it is a standard unit for mass. Here, 1 amu is equal to the mass of either one proton or neutron and equals to 1 g/mol. Atomic mass unit is equal to 1/12^th of the mass of C-12 atom. For example, if average atomic mass of carbon is 12.01 thus, it is the mass of 1 carbon atom.

Interpretation Introduction

(b)

Interpretation:

Using the average atomic masses, the number of atoms of the sample should be determined.

8139.81 amu of nitrogen

Concept Introduction:

Atomic mass unit measures mass in an atomic scale, it is a standard unit for mass. Here, 1 amu is equal to the mass of either one proton or neutron and equals to 1 g/mol. Atomic mass unit is equal to 1/12^th of the mass of C-12 atom. For example, if average atomic mass of carbon is 12.01 thus, it is the mass of 1 carbon atom.

Interpretation Introduction

(c)

Interpretation:

Using the average atomic masses, the number of atoms of the sample should be determined.

13, 490 amu of aluminium

Concept Introduction:
