24
Why do we use moles?
Because atoms weigh too little and there is too many to measure
25
How many particles does a mole contain?
6.02 x 10^23
26
What is the formula for the number of moles?
Mass of what there is / average mole mass
27
What is the unit for the number of moles?
G/ gmol^1
28
What is the calculation for moles?
N= m/n
29
How can you predict ionic charges for elements?
Non metals are negative and metals are positive. Then use the groups to work out how many they would lose or gain.
