What does concentration measure?

Amount of solute in a certain volume of solvent

Definition of solute

The substance that's dissolved

Definition of solvent

The liquid the solute is dissolved in

Standard unit for concentration

Grams per cubic decimetre (g/dm3g/dm^3)

Convert: 1dm31 dm^3 to cm3cm^3

1000cm31000 cm^3

Formula for conc. in g/dm3g/dm^3

MassofSolute(g)Volume(dm3)\frac{Mass of Solute (g)}{Volume (dm^3)}

Formula for conc. in mol/dm3mol/dm^3

MolesofSoluteVolume(dm3)\frac{Moles of Solute}{Volume (dm^3)}

When to use g/dm3g/dm^3 for conc.

When mass of solute is known

When to use mol/dm3mol/dm^3 for conc.

When amount of solute measured in moles

High conc. vs low conc.

High conc. has more solute in same volume

Conc. of 25g NaCl in 1dm31 dm^3

25g/dm325 g/dm^3
