Make it concrete
Analogy
Moles and concentration is like changing a recipe: the particles, amounts and conditions decide what product you can make.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
Amount in moles equals mass divided by relative formula mass.
Concentration in g/dm3 equals mass divided by volume in dm3.
Balanced equations give reacting ratios in moles.
