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 1.69 g of quinine is dissolved in 25.0 g of cyclohexane, the freezing point of the solution is lowered by 4.33 ∘C. Look up the freezing point and ?f constant for cyclohexane in the Colligative Constants table. Calculate the molar mass of quinine.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
