The relative density of a metal = Weight of the metal in air / Loss in weight of metal in water = 210/(210-180) = 210/30 = 7.

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

Metal=210/(210-180)= 7

In the Same way

Relative density of liquid=(210-120)/(210-180)=90/30=3

Ans) 7,3

Dear Student

Relative density of metal = wieght in air / Change in weight of water
= (210) / (210 – 180)
Denstiy of metal = 7 g/cm²

I hope this answer will help you.
Thanks & Regards
