A solid weighs weighs 20g in air,a8.2g in a liquid and 18g in water. Calculate
i. Relative density of the body
ii. Relative density of the liquid
iii. Density of the liquid

Sagot :

Answer:

Weight of the body in air = 20gf ( Wa)

Weight of the body in water = 18gf ( Ws)

Weight of the body in liquid =18.2gf ( Wl)

Now,

The loss of weight in the water = 20 - 18 or, 2 gf

So the relative density of the body is = Wa / ( wa - ws )

= 20 / 2

= 10

2) The weight loss in liquid = 20 - 18.2 or, 1.8 gf

So the relative density of the liquid is =( Wa - Wl ) / ( Wa - Ws )

= 1.8 / 2

= 0.9
