Density of water is_________g/cm3 .
Hence, The density of water is 1 g/cm3 .
An object of mass 100 g has a volume of 20 cm3. Calculate the density of the object. If the density of water is 1 g/cm3. State whether the object will float or sink in water.
Equal masses of water and a liquid of density 2 g/cm3 are mixed together, then the mixture has a density of 4n g/cm3 , where n is ___.
