Show transcript
Concentration of an aqueous solution is the mass of solute dissolved in 1 dm³ of distilled water, in g/dm³.
The mass of one mole of solute is equal to the relative mass of the solute measured in grams.
Concentration can be expressed in g/dm³ or mol/dm³.
Equal volumes of solutions of the same concentration (in mol/dm³) have equal numbers of dissolved solute particles.
Volume can be measured in various units; 1 dm³ is equivalent to 1000 cm³.
