Interactive Chemistry Worksheets for Students
There are five chemical formula rearding the mole which you should know.
The units for the formulae may change depending upon the country, however the formulae are basically the same.
If you are studying senior chemistry at high school you should learn these formula and what each of the terms mean.
V(g) = the volume of a gas in litres. Unit L
VM = the volume of 1 mole of gas at a specified temperature and pressure. Unit L.mol-1
m = the mass of a substance in grams. Unit g
M = the molar mass of a substance. Unitt g.mol-1
q = the energy change in the reaction. Unit kJ
ΔHreaction = The molar heat of reaction. The energy change produced by one mole of reactant. Unit kJ.mol-1
N = The number of particles
NA = Avogadro's number. The number of particles in one mole
c = the concentration of a liquid in moles per litre. Unit mol.L-1 or M eg. 2.0 M H2SO4 solution
v = the volume of a liquid in litres. Unit L
