Chemistry- concentration and amount of substance exercises

Molarity

Concentration = amount/volume

Molarity = mole/litre

Click on each formula below to find its formula mass

Volume

Volume = amount/concentration

Volume = mole/molarity.

Mole

Mole = molarity X volume

Mass

Mass = mole X Formula mass

Mole = Concentration X volume(litres)

mole = 0.1 X 0.02 =0.002

Mass

Mass = mole X formula mass

Mass = 0.002 X 102 = 0.204 grams

Molarity,volume,moles, mass.
