Question

an empty density bottle weight 30 g when completely filled with water at 4 degree Celsius it weight 55 g and when filled with a unknown liquid it weight 70 g find the relative density of unknown 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

3

∴ Volume of density bottle = 32 cm

3

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

∴ density of the liquid = ∴

Volumeofliquid

Massofliquidonly

=

32cm /

24g

=0.75g/cm
