Specific gravity is a ratio of the weight of a substance to the weight of an equal volume of a substance chosen as a standard. The standard for liquid and solids is water while for gas is hydrogen.
Amount of displaced oil = 12.64 g — 9.12 g = 3.52 g
Amount of displaced water = 12.64 g — 8.57 g = 4.07 g
5 - 10 x = 3 10 x = 5 - 3 10 x = 2 x = 10 : 5 x = 0.2 The rate is : 0.2 gallons / minute 5 - t * 0.2 = 0 t * 0.2 = 5 t = 5 : 0.2 t = 25 min Answer: After 25 minutes the container will be empty.
