Question

A measuring cylinder contains water up to the 36ml mark. When a stone is immersed in it, the water level rises up to 64ml. If the mass of the stone is 40g, find the density of the stone.

Answer 1

• Mass=40g
• Volume=64ml-36ml=28ml

We know

$\boxed{\sf Density=\dfrac{Mass}{Volume}}$

$\\ \rm\longmapsto Density=\dfrac{40}{28}$

$\\ \rm\longmapsto Density=\dfrac{10}{7}$

$\\ \rm\longmapsto Density=1.4g/ml$
