Question

an empty bottle of 25ml capacity weighs 22.6g. when completely filled with turpentine oil, it weighs 43.8g. find density of turpentine oil

Answer 1

Mass of empty density bottle = 30 gm

mass of density bottle with water in it  62 gm

Mass if density bottle with the liquid = 54 gm

Mass of water only = 62-30=32 gm

(a) Now volume of 1 g of water = 1cm3

∴ Volume of density bottle = 32 cm3

(b) Mass of liquid only = 54-30=24 gm

∴ density of the liquid = ∴VolumeofliquidMassofliquidonly

=32cm324g=0.75g/cm3
