Chemistry Calculations: Density, Avogadro's Number, Molar Mass, Stoichiometry, and Mass %, Schemes and Mind Maps of Stoichiometry

Texas Health and Science UniversityStoichiometry

A list of the most common relationships used in general chemistry calculations. It covers concepts such as density, Avogadro's Number, molar mass, stoichiometry, and mass percent. examples of how to use these concepts as conversion factors for various calculations.

What you will learn

  • How can density be calculated directly?
  • What is the role of stoichiometry in calculating moles in a balanced reaction?
  • How can density be converted from mass to volume?
  • How can molarity be calculated from moles and liters?
  • What is the relationship between Avogadro's Number, moles, and number of things?
