What textbook chapter and section from Chemistry: The Central Science can I use to learn this content: 
1.1.A.1
One cannot count particles directly while
performing laboratory work. Thus, there must
be a connection between the masses of
substances reacting and the actual number of
particles undergoing chemical changes.
1.1.A.2
Avogadro’s number (N = 6.022 × 1023 mol−1
)
provides the connection bet A
ween the number
of moles in a pure sample of a substance and
the number of constituent particles (or formula
units) of that substance.
1.1.A.3
Expressing the mass of an individual atom
or molecule in atomic mass units (amu) is
useful because the average mass in amu of
one particle (atom or molecule) or formula
unit of a substance will always be numerically
equal to the molar mass of that substance
in grams. Thus, there is a quantitative
connection between the mass of a substance
and the number of particles that the
substance contains.
EQN: n = m/M
1.1.A
Calculate quantities of a
substance or its relative
number of particles using
dimensional analysis and the
mole concept.
