Mole Concept
and
Stoichiometry
, Vapour Density
Vapour density = Wt. of a certain volume of a gas
of a gas Wt. of an equal volume of H2
OR
Vapour density = Wt. of 1 litre of gas
of a gas Wt. of 1 litre of hydrogen
, Relative molecular mass [RMM]
( Molecular Weight)
It is the number of times one molecule of a substance is
heavier than 1/12th the mass of an atom of carbon ( C12).
, RMM = 2 x Vapour Density
