Question

Derive the relationship between molal mass
of Solute
and lowering of vapor pressure.​

Answer 1

$\tt \red{your \: answer}$

W1 and M1 are the mass and molar mass of the solvent, respectively. W2 and M2 are the mass and molar mass of the solute, respectively. Hence, it derived the relationship between the relative lowering of vapour pressure and molar mass of the non-volatile solute.
