Question

The volume of a $500g$ sealed packet is $350c{m}^3$ what will be relative density of the packed packet if density of water is $1g/c{m}^3$

• A. $2.22$
• B. $60$
• C. $1.43$
• D. $15$

Answer 1

The correct option is C $1.43$

Volume of sealed packet $=350c{m}^3$
Mass of sealed packet $=500g$
density of the packet $=\frac{M}{V}=\frac{500g}{350c{m}^3}=1.43g/c{m}^3$
Relative density $=\frac{\text{Density of the packed pocket}}{\text{Density of water at the same temperature}}$
$=\frac{1.43g/c{m}^3}{1gc{m}^3}=1.43$
Thus, the relative density of the packed packet is $1.43$
