**Question**

**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] **

**Answer**

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.
