The chemical mole
by Sean Johnson
1. Concentration of a solution (C) = number of moles/volume (dm^3)
2. One mole of gas at "STP" (Standard Temperature and Pressure) occupies 22.4 dm^3 at 101KPa at 273 Kelvin (0•C)
3. Moles = Mass/Molar Mass
4. A mole is a quantity; it contains 6.02 x 10^23 particles. This is known as Avagadro's constant.
5. One mole of gas occupies 24 dm3 at room temperature (25•C) and standard pressure (101KPa)
6. Gas Law: PV = nRT, where R is the 'gas constant' (8.31 J /mol dm^3)
