Answer:

Substance 4

Explanation:

Density is defined as mass per unit volume. A substance floats in another when its density is less than that of the substance on which it floats.

If an object is immersed in a denser liquid, it will sink

Since the density of water is 1 g/cm^3, any substance whose density is less than that of water will float in it.

If we look at the table, substance 4 has a density of 0.5g/cm^3. Hence, substance 4 is expected to float in water.
