Reacting Mass Series 5: cm3 and moldm3
Here we look at the use of a rearrangement triangle that connects moles, volume of solution and concentration of solution. Concentration = mol/dm3 Moles = concentration x dm3 dm3 = mol/concentration.

Equilibrium reaction quotient expressions
Chemical Equilibrium Part 4 for Mr. Newton's AP Chemistry class. This video explains how to use the "Q" or the reaction quotient expression to take any starting condition and figure out which direction the reaction will proceed in to reach equilibrium by comparing it to the equilibrium constant expression
