Question

A piece of stone of mass 113g sinks to the bottom in
water contained in a measuring cylinder and water level
in cylinder rises from 30ml to 40 ml. Calculate the density
of the stone.​

Answer 1

Answer:

11.3g

Explanation:

Mass of the stone =113g

Volume of stone = Volume of water displaced =40ml−30ml=10ml

Density of stone = Mass of stone/Volume of stone =113/10 = 11.3g/ml

Answer 2

Answer:

Given:

• A piece of stone of mass 113g sinks to the bottom in water contained in a measuring cylinder and water level in cylinder rises from 30ml to 40 ml.

Find:

• Calculate the density of the stone.

Know terms:

1. Density = (D)
2. Mass = (m)
3. Volume = (v)

Using formula:

★ ${\sf{\underline{\boxed{\orange{\sf{D = \dfrac{m}{v} }}}}}}$

Calculations:

$\longrightarrow\sf{D = \dfrac{113}{30 - 20}}$

$\longrightarrow\sf{D = \dfrac{113}{10}}$

$\longrightarrow{\sf{\underline{\boxed{\red{\sf{D = 11.3 \: g/ml}}}}}}$

Therefore, density of the stone is 11.3 g/ml.
