(a) derive the equations used in this problem based on forces and the experiment on specific gravity. A cylinder of solid material weight 10.5 kg i the air, and 9.00 kg when submerged in water and 3 kg when submerged in another liquid.
(b) determine the volume of the cylinder without using the density.
(c) determine the density of the cylinder.
(d) determine the density of the unknown liquid and try to identify it. You most look up the values in litriture, periodic table, or CRC handbok.
