A 1 molar solution
is a solution in which 1 mole of
a compound is dissolved in a total
volume of 1 litre.
For example:
The molecular weight of sodium chloride
(NaCl) is 58.44, so one gram molecular
weight (= 1 mole) is 58.44g. If you
dissolve 58.44g of NaCl in a final
volume of 1 litre, you have
made a 1M NaCl solution.
To make a 0.1M NaCl solution, you
could weigh 5.844g of NaCl and dissolve
it in 1 litre of water; OR 0.5844g
of NaCl in 100mL of water (see animation
below); OR make a 1:10 dilution of
a 1M sample.
Making a 0.1M NaCl solution (w/v)
Many of the solutions you will use
are described in terms of their molarity,
so check that you are comforable
with the concept by describing how
you would make 500mL of a 0.05M NaCl
solution.
