To know how to define molar volume of gases at room temperature and pressure
To be able to use the molar volume in calculations involving the masses of solids and volumes of gases
To understand how to use Avogadro’s law to calculate volumes of gases involved in gaseous reactions.
2. CONCENTRATION with mol and grams per dm3 and interchanging between the two
Objectives:
STARTER: To know how to interconvert between cm3 and dm3 and to work out the concentration equation

To be able to calculate concentrations in mol dm-3 (H)
To understand how to interconvert between mol dm-3 and g dm-3 (H)
3. PERCENTAGE YIELDS + moles SEPARATE or TRIPLE
Objectives:
To understand the difference between the actual yield and the theoretical yield
To be able to calculate the percentage yield of a reaction from the actual yield and the theoretical yield
