2. (a) The density of a material is the mass of it per unit volume -
It is measured in ga./c.c. or lb./cu. ft.
The 'relativa daniaty of a material is the ratio of its density to that of water. It is simply a number or ratio without unit. (b) The density of crystals of copper mulphate can he found by using
turpentine and a specific gravity bottle. The S.as bottls with its stopper is weighed empty (Wo). The copper sulphate cryst are then placed into it and is weighed (Wy). Turpantine of kagün density is added into it. The stopper is inserted and exceas turpentine escapes and is wiped day on the outside. It is then weighed again (2). The content is then emptied and cleaned before the hottie is filled with turpentine inc' stoppar änserted. weighed again when the outside is dried
