Question

IF A SAMPLE OF METAL WEIGHS 210 G IN AIR ,180 G IN WATER AND 120 G IN LIQUID THEN
a R.D.OF METAL IS 3
b R.D. OF METAL IS 7
c R.D. OF LIQUID IS 7
d R.D. OF LIQUID IS 1/3

Answer 1

relative density = (weight of body in air -weight of body in liquid)/(weight of the body in air – weight of body in water)

weight of the body in air  =210g

weight of body in water = 180g

weight of body in liquid = 120g

 

(210-120) / (210-180) = 3

 

relative density = 3
