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).
