| Question | Answer |
| using Avogadro's constant to find number of moles | number of particles in substance / Avogadro's Constant (6.022 x 10ˆ23) |
| finding number of moles | mass (g) / molar mass (g/mol) |
| finding molarity / concentration (mol/dm3) | number of moles (mol) / volume (dm3) |
| finding number of moles (gas) | volume (dm3) / molar volume (24dm3/mol) |
| % by mass | (molecular mass / total formula mass) x100% |
| % purity | (pure product mass / total mass) x100% |
| % yield | (experimental yield / theoretical yield) x100% |
| concentration / dilution | M1V1 = M2V2 |
