How to find the Emperical Formula of a compound
We look at how to find the Emperical Formula and what the difference is between the Emperical formula of a compound and the Molecular Formula of a compound.
Chem 11 - How to find the % composition of elements
We take a look at how to find the % composition of a compounds elements. Yes I meant 2 oranges and 8 apples :)
Chem 11 - Density and Molar Volume
We take a look at the density formula and how we can relate it to Molar mass and Molar Volume
Converting Molecules to Volume
We take a look at how to convert from molecules to Molar Volume using our conversion factors.
How to convert Mass to Molecules
We take a look at how to convert from mass to molecules, going through the Moles and using Avagadro's Number. Then we take a look at how to find the mass of a certain number of molecules of a substance.
How to Convert Moles to Mass
We take a look at how to convert Moles to Mass and then Mass to Moles using the Molar mass of elements found on the periodic table of elements.

Chem 11 - 2.2 - Significant figures part 2
We look at how to multiply and divide as well as add and subtract taking into consideration significant figures.
Chem 11 - 2.2 - Significant figures part 1
We look at what significant figures are and what they mean. Essentially, they mean how precise a measurement is. When we get the same measurement over and over, we get an accurate and precise measurement.
