Question

Relationship between molarity and molality

Answer 1

Molarity (M) is defined number of moles of solute per litre of solution . Molality (m) is defined as number of moles of solute per kilogram of solvent . When water is solvent and the concentration of solution is low , these difference can be negligible ( d= 1.00g/ mL)

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.
