An empty relative density bottle weighs 25g.it weighs 65g when filled with a liquid and 75g when with water.caculate the density of the liquid.

Ww = 75-25 = 50 g = Wt of water.

Ww = V * D = 50 g.
V * 1g/cm^3 = 50
V = 50 cm^3. = Vol. of water.

65 - 25 = 40 g. = Wt. of the liquid.

D = 40g/50cm^3 = 0.80 g/cm^3. = Density of the liquid.
