The mass of particles

The mass of particles. Relative isotopic mass, Relative atomic mass, Relative molecular mass, The mole. The relative isotopic mass (I r ) of an isotope is the mass of an atom of that isotope relative to the mass of an atom of 12 C taken as 12 units exactly. Relative isotopic mass.

Empirical Formula

Molecular Formula A molecular formula shows the elements that a compound is made out of and the number of atoms of each element present in one molecule of the compound. The numbers are shown written as subscripts. e.g. The molecular formula of butane is C 4 H 10

The Mole

The Mole. What is a mole??? As we have seen in previous chapters the masses of atoms are very small e.g. mass of proton = 1.67 x 10 -27 kg mass of neutron = 1.67 x 10 -27 kg mass of electron = negligible
