Quinine is a natural product extracted from the bark of the cinchona tree, which is native to South America. Quinine is used as an antimalarial agent. When 2.04 g of quinine is dissolved in 25.0 g of cyclohexane, the freezing point of the solution is lowered by 5.23 °C. Look up the freezing point and K+ constant for cyclohexane in the Colligative Constants table. Calculate the molar mass of quinine. molar mass: 315.42 Incorrect Answer g/mol
