A saline solution has a volume of 200 cm3 and a mass of 216 g. The density of pure water is 1.00 g/cm3. How does the density of the saline solution compare with the density of pure water?
Its density is higher than that of pure water.
Its density is lower than that of pure water.
Its density is the same as that of pure water.
It is impossible to say with only this data.
