The molar mass of an unknown compound must be determined, using a solvent that has a freezing point of 30.16 ° C. A solution of 0.617 g of p-dichlorobenzene, C6H4Cl2, in 10.00 g of the solvent, had a freezing point of 27.81 ° C, while 0.526 g of the unknown compound in 10.00 g of the solvent caused the freezing point to drop to 26.47 ° C. Calculate the molar mass of the unknown compound.
