Topics 5
- Atomic (isotopic) and molecular masses; atomic mass unit as 1/12 of the mass of carbon-12; mole, Avogadro's number and gram molecular volume
- Percentage composition; empirical and molecular formulae
- Chemical equivalents: equivalent weight, variable equivalent weight, gram equivalent; relation with molar mass and valency; equivalent weights of acids, bases, salts, oxidising and reducing agents
- Concentration terms: percentage (w/w, w/v), normality, molarity, molality, mole fraction; normality and molarity equations
- Stoichiometric calculations: mass-mass, mass-volume and volume-volume relationships; limiting reagent
