Question

An empty density bottle weighs 25.5g. When filled with water, it weight 55.5g. When filled with liquid, it weight 46g. Find the density and the relative density of the liquid​

Answer 1

Answer:

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 = 1cm

∴ Volume of density bottle = 32 cm

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

∴ density of the liquid = ∴
