Question

A stone weighing 100 g is submerged in a measuring cylinder holding 50 ml of water. The water rises to 75 mL. What is the density of the substance?

Answer 1

Given:-

Mass of stone = 100 g

Volume of stone$=(75-50)mL=25mL=25c{m}^3$

Finding density of the stone:-

$density=\frac{mass}{volume}=\frac{100g}{25c{m}^3}=4\frac{g}{c{m}^3}=4000\frac{kg}{m^3}$

Hence density of substance is $4000\frac{kg}{m^3}$.
