Caryophyllene is a non-electrolytic organic compound found in the essential oil of cloves. To extract the caryophyllene from a sample of cloves, a researcher soaked cloves in chloroform. If 207 mg of caryophyllene dissolved in 1.00 g of chloroform resulting in a solution with a boiling point 3.68°C higher than pure chloroform, what is the molar mass (g/mol) of caryophyllene?

chloroform Kb = 3.63°C/m

A sample of chloroform is found to contain 12.4 g of carbon, 109.9 g of chlorine, and 1.04 g of hydrogen. If a second sample of chloroform is found to contain 28.6 g of carbon, what is the total mass of chloroform in the second sample?
