5. A solution containing 0.5126 g of naphthalene (molar mass = 128.17 g mor') in50.00 g of CCl4 gives a boiling point elevation of 0.402°C. While a solution of0.6216 g of unknown solute in the same mass of the solvent gives a boiling pointelevation of 0.647°С. Find the molar mass of the unknown solute.(K for CCl4 = 5.03 K kg mor' of solvent) |
