In
attempting
to
carry
out
a
reaction
in
the
laboratory,
every
chemistry
student
has
learned
that
a
vital
step
in
the
procedure
deals
with
the
calculation
of
the
amount
of
starting
materials
required
and
the
amount
of
product
that
is
expected
to
be
produced.
在实验室里进行的化学反应实验中,每个学化学的学生都已经认识到,在整个过程中,关键的一步就是对所需初始物质的数量以及预期会产生的物质的数量进行计算。
Such
calculations
are
also
required
when
chemical
reaction
are
carried
out
on
an
industrial
scale.
而在工业规模的化学反应中,这种计算同样是必须的。
