mol frac, m%, molarity, molality

Mol frac

mol of component / total mol

molality (m)

mol solute / kg solvent

molarity (M)

mol solute / volume soln (L)

mass percent

grams solute / total grams soln (can be made 100 if not given)

all times 100 for percent

density

grams soln / ml soln

volume percent

ml solute / total ml soln

all times 100

mass volume percent

g solv / total ml soln

all times 100

units are %m/v

solvent

the one with more, what a solute in dissolved IN

solute

the one with less, the one being dissolved

ΔT_f

T_pure - T _soln

(m) = molal

ΔT_b

T_soln - T_pure

imK

(m) = molal

molecular weight
