Question

Look at the following figure and answer the questions based on it.
$1.$Name the device used in the given figure.
$2.$Find the volume of the stone
$3.$Find the density of the stone.

Answer 1

Initially water=$80ml$

Final reading of water=$130ml$

Mass of stone=$250gm$

$1.$ measuring cylinder is used here.

$2.$ mass of stone have a volume of $130-80=50ml$.

$3.$ For density of stone=$d=\frac{m}{v}$

$50=\frac{250}{d}$

$d=5g.ml$

or $d=5g/c{m}^3$
