molal is a unit for concentration =
Molality is therefore a concentration unit that is temperature- and pressure-independent.
molar = moles / (1L of aqueous solution),
is a concentration unit that is
At 25°C the density of dilute aqueous solutions is ≈1000 g/L, and molality ≈ molarity; however the density varies with concentration, temperature, etc.
