Explanation:The concentration of a solution can be given in moles of solute dissolved per kilogram of solvent.
This is known as molality.
(Not to be confused with molarity which is a different measure of concentration.)
Molality is given the symbol m.
molality = moles of solute ÷ mass of solvent in kilograms
m = n(solute) ÷ mass(solvent in kg)
A solution containing 3 moles of solute per kilogram of solvent for example, is said to be 3-molal or 3m.

This led to the principle of uniformitarianism which states that the geologic processes now are the same with the ones in the past.
