hlo mate pls mark this answer as a brainliest answer . I will sure follow u.
Explanation:
Given that,
Weight in air =120g
Weight in water =80g
Weight in liquid =60kg
We know that,
Relative density of solid
=
W
(air)
−W
(water)
W
(air)
=
120−80
120
=
40
120
=3
Relative density of liquid
=
W
(air)
−W
(water)
W
(air)
−W
(liquid)
=
120−80
120−60
=
40
60
=
2
3
Hence, the relative density of the solid and that of the liquid are 3,3/2 respectively
hope this helps you.
