Question

Differentiate between molarity and molality. 2 marks

Answer 1

Molarity is defined as the no. of moles of solute present in per litre of solution
*it is denoted by capital m(M)
*M=v2(given volume)/M2molecular volume×1000/V1(ml)

Molality is defined as the no. of moles of solute present in per kg of the solvent
*it is denoted by small m(m)
*m=w2/M2×1000/w1(g)
