Equation for moles (mol)
Number of Moles(mol) = Mass(g) / Relative Formula Mass(Ar, Mr)
Equation for particles
Number of particles = Number of moles(mol) x Avogadro's Number (6.02x10²³)
What is Avogrado's constant?
6.02 x 10²³
Formula for concentration
Concentration (g/dm³) = Mass of solute(g) / Volume (dm³)
Formula for volume of gas
Volume of gas(dm³) = Mass of gas(g) / Relative formula mass (Ar, Mr)
How to calculate Rf value
Rf = Distance traveled by substance / Distance traveled by solvent
How to calculate atom economy
Atom economy = (Relative formula mass of desired product / Relative formula mass of all reactants) x 100
How to calculate percentage yield
Percentage yield = (Mass of product actually made / Maximum theoretical mass of product) x 100
