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 1.99 g of quinine is dissolved in 25.0 g of cyclohexane, the freezing point of the solution is lowered by 5.10 °C. The freezing point and Kf constant for cyclohexane can be found here. Calculate the molar mass of quinine.
Red phosphorus is fairly stable, while white phosphorus will ignite spontaneously in air above 50 C. Determine the change in entropy for the conversion of the white form to the red form
