Q

Concentration (mass by volume; m/v)

A

mass of solute (grams) / volume of solution (millilitres) x 100

17
Q

Concentration (moles/litre)

A

c = n / V (concentration in molar = amount of mol / volume in litres)

18
Q

Molarity

A

Concentration measured in the unit mol/L or molar (M).

19
Q

Dilution Formula

A

c1V1 = c2V2 (initial concentration x initial volume = final concentration x final volume).
