CH 3 The conservation of atoms in chemical reactions leads to the principle of conservation of matter and the ability to calculate the mass of
products and reactants. As a basis for understanding this concept:
3. b. Students know the quantity one mole is set by defining one mole of carbon-12 atoms to have a mass of exactly 12 grams.
The mole concept is often difficult for students to understand at first, but they can be taught that the concept is convenient in chemistry just as a
dozen is a convenient concept, or measurement unit, in the grocery store. The mole is a number. Specifically, a mole is defined as the number of
atoms in 12 grams of carbon-12. When atomic masses were assigned to elements, the mass of 12 grams of carbon-12 was selected as a standard
reference to which the masses of all other elements are compared. The number of atoms in 12 grams of carbon-12 is defined as one mole, or
12
conversely, if one mole of C atoms were weighed, it would weigh exactly 12 grams. (Note that carbon, as found in nature, is a mixture of isotopes,
including atoms of carbon-12, carbon-13, and trace amounts of carbon-14.) The definition of the mole refers to pure carbon-12.
The atomic mass of an element is the weighted average of the mass of one mole of its atoms based on the abundance of all its naturally occurring
isotopes. The atomic mass of carbon is 12.011 grams. If naturally occurring carbon is combined with oxygen to form carbon dioxide, the mass of one
mole of naturally occurring oxygen can be determined from the combining mass ratios of the two elements. For example, the weight, or atomic mass,
of one mole of oxygen containing mostly oxygen-16 and a small amount of oxygen-18 is 15.999 grams.

3. c. Students know one mole equals 6.02 × 10 particles (atoms or molecules).
12
A mole is a very large number. Standard 3.b describes the mole as the number of atoms in 12 grams of C. The number of atoms in a mole has been
23
found experimentally to be about 6.02 × 10 . This number, called Avogadro’s number, is known to a high degree of accuracy.
3. d. Students know how to determine the molar mass of a molecule from its chemical formula and a table of atomic masses and how to convert the
mass of a molecular substance to moles, number of particles, or volume of gas at standard temperature and pressure.
The molar mass of a compound, which is also called either the molecular mass or molecular weight, is the sum of the atomic masses of the
constituent atoms of each element in the molecule. Molar mass is expressed in units of grams per mole. The periodic table is a useful reference for
finding the atomic masses of each element. For example, one mole of carbon dioxide molecules contains one mole of carbon atoms weighing 12.011
grams and two moles of oxygen atoms weighing 2 × 15.999 grams for a total molecular mass of 44.009 grams per mole of carbon dioxide molecules.
The mass of a sample of a compound can be converted to moles by dividing its mass by the molar mass of the compound. This process is similar to
the unit conversion discussed in the introduction to Standard Set 3. The number of particles in the sample is determined by multiplying the number of
moles by Avogadro’s number. The volume of an ideal or a nearly ideal gas at a fixed temperature and pressure is proportional to the number of
moles. Students should be able to calculate the number of moles of a gas from its volume by using the relationship that at standard temperature and
pressure (0°C and 1 atmosphere), one mole of gas occupies a volume of 22.4 liters.

5. Overview
The number of atoms in 12 grams of carbon-12 is defined as one mole, or
12
conversely, if one mole of C atoms were weighed, it would weigh exactly 12
grams. If naturally occurring carbon is combined with oxygen to form carbon
dioxide, the mass of one mole of naturally occurring oxygen can be determined
from the combining mass ratios of the two elements. For example, the weight, or
atomic mass, of one mole of oxygen containing mostly oxygen-16 and a small
amount of oxygen-18 is 15.999 grams. Molar mass is expressed in units of grams
per mole. The number of particles in the sample is determined by multiplying the
number of moles by Avogadro’s number. The volume of an ideal or a nearly
ideal gas at a fixed temperature and pressure is proportional to the number of
moles. Students should be able to calculate the number of moles of a gas from its

and 1 atmosphere), one mole of gas occupies a volume of 22.4 liters.
