Empirical formula
- Molecular formula
- actual ratio in
which atoms
combine
- relative Molecular
mass (Mr)
- can be found using
mass spectrometer
- is equal to sum of
relative atomic mass
(Ar) of all the atoms
- relative atomic mass (Ar) is the
mass of atom as compared
to carbon-12 atom
- relative atomic mass (Ar) is the
mass of atom as compared
to carbon-12 atom
- can be found using
mass spectrometer
- simple multiple (n)
of emperical
formula
- n = relative molecular mass (Mr) /
emperical mass
- molecular formula =
n x emperical formula
- molecular formula =
n x emperical formula
- n = relative molecular mass (Mr) /
emperical mass
- actual ratio in
which atoms
combine
- simplest ratio in
which atoms
combine
- empirical mass
- can be
found by
experiment
- steps
- find the ratio of actual
mass of elements
- convert mass ratio to
mole ratio
- no of moles = given
mass / mass of 1
mole
- no of moles = given
mass / mass of 1
mole
- reduce mole ratio
to simplest ratio
- write empirical
formula from simples
mole ratio
- find the ratio of actual
mass of elements
- steps
