Question

Define molarity and molality .​

Answer 1

Molarity:-

molarity is the number of moles of solute dissolved per liter of solution.

It is denoted by capital M

Molarity = Mole solute/Litres of solution

Molality:-

Molality is then the number of moles of solute per kilogram of the solvent.

it is denoted by small m.

Answer 2

MOLARITY is defined as number of moles of solute dissolved per liter of solution. it is denoted by M.

a 1M solution contains 1 mole of solute per liter of solution.

MOLALITY is defined as number of moles of solute dissolved per kg of solvent. it is denoted by m .

a 1m solution contains 1 mole of solute per kilogram of solvent.
