Activity 1. Moles, solutions and volumes
Watch the first 2 minutes and 45 seconds of the video. Use it to construct a formula triangle which connects Volume (V/dm3) , Concentration (moles/dm3) and the number of moles n

A lot of reactions in the laboratory involve small volumes. It is often more convenient to work in cm3. This means we need to convert between dm3 and cm3 .
remember 1dm3 = 1000 cm3
