Question

what is the difference between molarity and molality​

Answer 1

Explanation:

MOLARITY

It is the no. of moles of the solute dissolved per litre of the solution. it's unit is mol per litre...

M=(given mass/ molar mass) *(1000/vol. of solution)

MOLALITY

It is the no. of moles of the solute dissolved per 1000g of the solvent.

m=(given mass/ molar mass) *(1000/mass of solvent)

Answer 2

Answer:

Molarity (M) is defined as the number of moles of solute per liter of solution.

Molality (m) is defined as the number of moles of solute per kilogram of solvent.
