The course is focused on the mastering of the basic chemical calculations necessary for the completion of laboratory exercises and other follow-up courses. Its contents include calculations based on the stoichiometry of chemical reactions (the quantity of reactants and products), on the expression and recalculation of mixtures composition, calculations based on the state equation of ideal gas and material balance of simple processes.

Last update: Rubešová Kateřina doc. Ing. Ph.D. (01.08.2019)

Students will be able to:

  • use and convert the values of quantities using SI units,
  • express and recalculate mixture and compound composition using various quantities,
  • calculate stoichiometry problems (quantity of reactants / products) including the application of conversion, yield or loss,
  • balance the mass of simple processes (solution preparation or dilution, crystallization)
