1
Q
Number of moles
A
No of moles = mass / relative mass
2
Q
Mass
A
Mass = number of moles x relative mass
3
Q
Number of moles when not given mass
A
Number of moles = number of atoms / AVOGADRO’S number
4
Q
Volume
A
Volume = mass / concentration
5
Q
Concentration
A
Concentration = mass / volume
6
Q
Number of moles when given concentration or volume
A
No of moles = concentration x volume
7
Q
Volume when not given mass
A
Volume = no of moles x molar volume
Molar volume = 24dm3
