Question

A solid weights 75 g f in air,70.5 g f in water and 66g f in a liquid . Calculate the relative density of the liquid .

Answer 1

Hi..

Heres ur answer..


Hope this helps u!!

Answer 2

relative density of liquid

     = density of liquid / density of water
     = buoyancy force in liquid / buoyancy force in water
     = Loss of weight in liquid / loss of weight in water
     = [ weight of object  in air - weight of object in liquid ] / [ weight of object in air - weight of object in water ]

     = [ 75 - 70.5 ] / [ 75 - 66 ]
     = 4.5 / 9
     = 0.5

Density of liquid = 0.5 * density of water
             = 0.5 * 1000 kg / m^3
                 =  500 kg/m^3
