The volume of a solid of mass 500g is 350 cc
- What will be the density of the solid?
- What will be the mass of water displaced by this solid?
- What will be the relative density of the solid?
- Will it float or sink in water?
[Ans. (a) 1.42 g/cc (b) 350 g (c) 1.42 (d) it will sink in water]
Mass (m) = 500 g
Volume (V) = 350 cc
(a) Density = 500\over 350 = 1.42 g/cc
(b) The solid will displace water equal to its own volume.
The volume of water displace = 350 cc
Mass = volume × density
= 350 × 1 = 350 g
(c) Relative Density = 1.42\over 1 = 1.42
(d) Since the relative density of the solid (1.42) is greater than the relative density of water, therefore, the solid is heavier than water and hence it will sink in water.
