Question

an empty density bottle weights 26 g. when completely filled with water, it weighs 54 g. when completely filled with brine solution its weight 58 g.calculate 1. volume of the bottle. 2. density of brine solution

(please answer this question in process)​

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 = 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
