Question

material density (g/cm3) aluminum 2.7 benzene 0.9 magnesium 1.7 water 1 ice 0.9 if all of these substances were placed together in the same container, which would end up on the top? choose the correct answer benzene iron magnesium aluminum

Explanation:

Step1: Understand density principle

The substance with the lowest density will float on top when substances are placed together in a container.

Step2: Compare given densities

We have aluminum density = 2.7 g/cm³, benzene density = 0.9 g/cm³, magnesium density = 1.7 g/cm³, water density = 1 g/cm³, iron density = 7.8 g/cm³. Among them, benzene has the lowest density.

Answer:

Benzene
