Annotation -
The course presents an introduction to calculations common in following courses of Chemistry, Laboratories, Chemical Engineering etc. The discussed toppics will include: system of quantities and units, relations between different quantities (e. g., quantification of mixture composition), applications of Ideal Gas Law, and elementary material balances (including mixture preparation, crystallization and simple systems with chemical reactions).

Aim of the course -

Students shall be able:

  • to express amount, composition and other properties of a system using basic SI and other units,
  • to derive, rearrange and solve equations based on definitions and selected laws
  • to derive and solve material balance equations for simple systems without and with chemical reactions
