1.	In a 103 L sample of hard water, CaSO4 & MgSO4 are present. If elevation in boiling point is 0.00208∘ C, then calculate the hardness of water in terms of ppm of CaCO3. (Kb for H2O=0.52 Kkgmol−1)
Answer» In a $10^{3} L$ sample of hard water, $C a S O_{4} & M g S O_{4}$ are present. If elevation in boiling point is ${0.00208}^{\circ} C$ , then calculate the hardness of water in terms of ppm of $C a C O_{3}$ . ( $K_{b}$ for $H_{2} O = 0.52 K k g m o l^{- 1}$ )
