Q.) Some bottles of colourless liquids were being labelled when the technicians accidentally mixed them up and lost track of their contents. A 15.0 ml sample withdrawn from one bottle weighed 22.3 g. The technicians knew that the liquid was either acetone, benzene, chloroform or carbon tetrachloride (which have densities of 0.792 g/cm³, 0.899 g/cm³, 1.489 g/cm³, and 1.595 g/cm³, respectively). What was the identity of the liquid?
