Course Module

Module 1: Amount of substance. Calculations using chemical formulas.

  • Lesson 22: The mole - the unit of amount of substance. Avogadro's number
  • Lesson 23: Molar mass
  • Lesson 24: Molar volume
  • Lesson 25: Relative density of gases

Expected Learning Outcomes

  • Knows the unit of measurement for the amount of substance, molar volume of gases at standard conditions, Avogadro's number.
  • Explains the essence of the physical quantity "amount of substance".
  • Establishes the relationship between physical quantities (mass, molar mass, volume, molar volume, amount of substance).
  • Calculates the number of particles (atoms, molecules, ions) in a given amount of substance, mass, volume; molar mass, mass and amount of substance; the volume of a given mass or amount of substance of a gas at standard conditions; the relative density of a gas relative to another gas, choosing and justifying the solution method.
  • Draws conclusions about the significance of mathematical knowledge for solving chemical problems.

By the end of this course, you will have a strong foundation in stoichiometry and be able to perform calculations involving moles, molar mass, and gas volumes. You will also develop a deeper understanding of the relationship between macroscopic properties of substances and the microscopic world of atoms and molecules.
