In science, the aggregate containing 6.02 × 10 ^ 3 particles
is regarded as a unit, which is called mole. It is the unit
that represents the amount of matter (symbol is n), which is
called "mole" for short, the unit symbol is mol. The carbon atom
of 1mol contains 6.02 × 10 ^ 3 carbon atoms with a mass of 12g.
The sulfur atom of 1mol contains 6.02 × 10 ^ 3 sulfur atoms
with a mass of 32g. The mass of a 1 mol substance is usually
called the molar mass of the substance (symbol is m). The unit
of molar mass is gram/mole, which is read as "gram per mole"
(the symbol is "g/mol"). For example, the molar mass of water
is 18 g/mol, which is written as m (H Ψ o) = 18 g/mol. What
is the relationship between the mass (m), the amount (n) and
the molar mass (m) of a substance?
The formula is as follows: n = m/m, M = n × m, M = m/N general
formula: n (mass) = n (number of particles)/Na (Avogadro constant)
= m (mass)/M (molar mass) = V (gas volume)/VM (molar volume: gas
volume: 22.4l for 1mol under STP (standard condition: 273k (0 ℃) 101kpa))
= C (mass concentration) × V (total volume of solution).
