Question

.  1.250 g of naphthalene was dissolved in 60 cm3 of benzene and freezing point of the  

                        solution was found to be 277.515 K, while that of benzene 278.495 K. Density of

                        benzene =0.880 g cm–3, Kf =5.1 K per 1000 g benzene. Calculate the molecular mass of

                        naphthalene.       

Answer 1

Molecular mass of naphthalene=128.17g
