Question

Calculate the molar mass of the unknown. Use the chart to determine the identity of the unknown based on the calculated experimental molar mass of compound 

Mass of tube 24.1808(g)

Mass of test tube +Naphthalene (g)=33.4506

Mass of test tube+ naphthalene +unknown (g) =34.6750

Time when crystals first appeared seconds = 23 C

Temperature whiv crystals first appeared 76.08 C

Molarity of naphthalene/ unknown solution = .6071
