The concentration of a solution is often measured using units of
mol/dm3
concentration of a solution = amount of
substance
(
mol
) /
volume
(
dm3
)
If 1.00 mole of solute is dissolved to form a solution that has a volume of 1.00dm3, the solution has a concentration of
1.00mol/dm3.
Occasionally
concentrations
are expressed in g/dm3.
If
10.0g
solute is dissolved to form a solution that has a volume of 1.00dm3, the solution has a concentration of
10.0g
/dm3.
