A small bottle weighs $20 g$ when empty and $22 g$ when filled with water. When it is filled with oil it weighs $21.76 g$ . What is the density of oil?

Solution

weight of water $=$ weight of filled glass $-$ weight of empty bottle
$= 2 g$
weight of oil $= 21.76 g - 20 g = 1.76 g$
Relative density of oil $= \frac{d e n s i t y o f o i l}{d e n s i t y o f w a t e r} = \frac{\frac{m a s s o f o i l}{V o l u m e}}{\frac{m a s s o f w a t e r}{V o l u m e}}$
$= \frac{1.76}{2} = 0.88$
Relative density $= 0.88$
