Question

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 A 15.0 ml sample withdrawn from one bottle weighed 22.3 g. The technicians knew that the liquid was either acetone, benzene, chloroform or carbon tetrachloride (which have densities of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?
