A small bottle weighs 20 g. when empty and 22 g. when filled with wate

1.	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 ?
Answer» Bottle when filled with water gains 2 gTherefore,Mass of water = 2 gDensity of water = 1 g/cm³ Volume of bottle = Mass of water / Density of water= 2 g / (1 g/cm³)= 2 cm³ Density of oil = Mass of oil / Volume of bottle= (21.76 g - 20 g) / 2 cm³= 0.88 g/cm³ Density of oil is 0.88 g/cm³

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 ?

Answer»

Bottle when filled with water gains 2 gTherefore,Mass of water = 2 gDensity of water = 1 g/cm³

Volume of bottle = Mass of water / Density of water= 2 g / (1 g/cm³)= 2 cm³

Density of oil = Mass of oil / Volume of bottle= (21.76 g - 20 g) / 2 cm³= 0.88 g/cm³

Density of oil is 0.88 g/cm³
