Explain freezing point and kf constant for cyclohexane

Reference no: EM13285103

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 1.41 g of quinine is dissolved in 25.0 g of cyclohexane, the freezing point of the solution is lowered by 3.63 °C. The freezing point and Kf constant for cyclohexane can be found here. Calculate the molar mass of quinine.
