Resource summary

The mole
1 The mole
1.1 Formula Mass
1.1.1 1. Work out the chemical formula
1.1.1.1 eg. 2KO
1.1.2 2. Add all the RAM's together
1.1.2.1 eg. 2 x Potassium = 39 x 2
1.1.2.2 2 x Oxygen = 2 x 16
1.1.2.3 > 38 + 32 = 70
1.1.2.4 Found in the data boooklet
1.1.3 3. Finish the sum and the formula mass will be the total number
1.2 To work out moles/mass use the triangle and calculate what you don't know by using what you do know
2 The mole when used to calculate concentration
2.1 This triangle can be used in the same way as the other one but they can also be used together to calculate more complicated calculations. See jotters for practise or the National 5 Chemistry textbook
