The mole

• Relative atomic mass(RAM or Aᴿ)= Mass of one atom of an element/ 1/12(mass) of one atom of carbon-12
• The relative atomic mass of an atom, is the mass compared with that of an isotope of carbon-12 which has a mass of exactly 12
• You can find the relative molecular mass(RMM or Mᴿ) by adding the relative atomic mass of all the atoms in a molecule of the compound
• Avogadro's number is 6.02 × 10 ^ 23 , This is a mole
• Number of moles = Mass (g)/RAM
• mass = moles X RAM
• mass/moles = RAM
