- Avogadro's constant
- The number of atoms in 1g of hydrogen is 6.022 x 10^23
- Definition: The number of atoms in 12g of carbon 12.
- The mole contains this number of particles
- The number of atoms in 1g of hydrogen is 6.022 x 10^23
- Number of moles
- n = m/Mr
- n = c x v
- n = vol x 24
- n = PV/Rt
- n = m/Mr
