Mole Ratios

By Harish Appana Satya on May 5, 2013

The concept of mole ratios between the atoms in a molecule and the mole ratios between different compounds in a chemical reaction (and thus balanced chemical equations) are explored. This concept then leads into stoichiometry calculations.

Conversion Factors

By Harish Appana Satya on May 5, 2013

Different types of mole calculations are explored using the conversion factors of molar mass, concentration, and volume of a gas. An emphasis is placed on correctly setting up the calculations so that units cancel out.
