If you take a closer look back at the post on mole concept formulae, you would notice that I have arranged the formulae according to the states (i.e. solutions, gases, for all states). This is an example of how you can organize information for easy memorization.
As such, you should always remember that this formula is always application for all situations, whether solids, liquids, gases, solutions:
- mole = mass/ (molar mass)
- mole = (number of particles) / (Avogadro's constant)
When you see solutions (aqueous state), the following applies:
- mole = concentration in mol/dm3 x volume in dm3
- mass = concentration in g/dm3 x volume in dm3
When you see gases, the following apply:
- mole = volume of gas / molar volume
Now, you have three groups of information, and each group has 1 to 2 formula(e), making memorization and recalling them easier.
