Volume to density 1ml water equals g?
1 gram (approx)
When a stone is placed in a pail filled to the top 90 ml of water is displaced Explain how you know the volume of the stone is 90 cubic centimetres?
Water has a density of 1 gram of mass for each cc (or ml) of volume. An object with a density of less than 1 gram of mass for each cc of volume will float in water. An object with a density of more than 1 gram of mass for each cc of volume will sink in water. (But it may float in other liquids, depending on their densities.)
