A chemist is trying to identify a chemical by determining its molar mass. A sample weighing 0.75 grams was dissolved in 0.10 kilograms of benzene and the freezing point depression was determined to be 0.50° Celsius. Given the Kf for benzene of 5° Celsius kilograms per mole, what is the molar mass of the chemical in grams per mole to the nearest whole number?
