A known volume of a liquid is measured to have a mass of 2.5 kg. If the density of water is 1 g/cm³, determine the liquid's relative density.
💡 Hint: Ensure both values are in consistent units.
You have a mixture of two substances: one with a density of 0.5 g/cm³ and another with 1.5 g/cm³. If equal volumes of both are mixed, will the mixture float in water?
💡 Hint: Analyze the average density from the two densities.
