Boiling Point Elevation

Molality m=‌

x

W

×1000 .....(i)
Where, Molality =m
Number of mole of solute =x
Weight of solvent in grams =W
Moles of solute = mass of solute ∕ molar mass of solute
From eq. (i), (ii), (iii), we derive that elevation of boiling point is inversely proportional to the molar mass of the solute.
