So, if you pour water and vegetable oil into the same beaker they will not mix but they will separate out into 2 layers. Liquid water is more dense than vegetable oil. If you weigh 1.00 mL of vegetable oil it might have a mass of about 0.8 g so its density is about 0.8 g/mL or 0.8 g ml -1. If you weigh 1.00 mL of liquid water it will have a mass of about 1 g so its density is about 1 g/mL or 1 g mL -1. You could use a 1.00 mL pipette to acquire a sample of the liquid and weigh this. If you want to measure the density of liquids in the lab, it is much easier to use units of mass per unit volume in millilitres. You can use these cubes to determine the densities of some different solid substances like copper, iron, zinc etc. You probably have some 1 cm 3 cubes of different substances in your lab. Gold has a density of 19.3 grams per cubic centimeter, that is, 19.3 g/cm 3 or 19.3 g cm -3.Īluminium has a density of 2.7 grams per cubic centimeter, that is, 2.7 g/cm 3 or 2.7 g cm -3. The density of each substance is given in units of mass per unit volume, for our cubes this will be mass in grams per cubic centimeter, that is, g/cm -3 or g cm -3. We can also say that aluminium is less dense than gold because, for the same volume of the two substances, this volume of aluminium has less mass. Gold is said to be more dense than aluminium because, when we compare the same volume of the two different substances, this volume of gold has the greater mass. The other cube is made out of aluminium has a mass of only 2.7 grams. One cube is made out of gold and has a mass of 19.3 grams. Each cube measures 1 cm × 1 cm × 1cm so that each cube has a volume of 1 cm 3. The metallic elements aluminium and gold are both solids at room temperature and pressure.īy weighing a known volume of metal we can determine the density of each metal. You can determine, or measure, the density of solids, liquids and gases in the lab. Density is defined as the amount of mass per unit volume.
