In this lab experiment students are asked to determine the standard molar enthalpy of formation of magnesium oxide, MgO. Students are asked to use Hess's Law and the enthalpy changes of several other solution reactions during this...

As part of the "Basic Atomics" section of the Virtual Textbook, this site examines moles. The information presented defines moles in relation to Avogadro's number and then goes on to describe molar mass and molar volume.

An introduction to the mole, a unit of measurement that quantifies atoms and molecules.

This site deals with Amedeo Avogadro, his life, his contributions to chemistry, and his famous number.

This chemistry tutorial helps students understand that formula mass is the total of all the atomic masses of a chemical formula.

Heat is defined and explained; the concept of heat is related to the kinetic motion of particles and to temperature. Heat capacity and specific heat are explained. Sensible heat is compared to latent heat; reference is made to the heat...
