Camphor is a white solid that melts at 179.50°C. It has been used to determine the molecular weights of organic compounds because of its unusually large freezing-point-depression constant (39.7°C/m), which allows ordinary thermometers to be used. The organic compound is dissolved in camphor, and then the melting point of the solution is determined. If 1.08 g of an unknown compound is dissolved in 73.6 g camphor, the freezing point is found to be 177.09°C. What is the molecular weight of the unknown compound?

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.
