what are all the formulas for calculating Moles
Moles = Volume x Concentration
1. number of moles= mass/molecular weight (for solids)
2. number of moles= concentration*volume (for liquids)
(units 4 volume is dm cubed n the units 4 concentration is mol per dm cubed).
3. number of moles= volume/24
units in dm cubed
