Question

A 2.75 kg sample of a substance occupies a volume of 250 cm cube find its density in gram/centimetre cube

Answer 1

Answer

11 g/cm³

Explanation

Given:

A 2.75 kg sample of a substance occupies a volume of 250 cm³

To Find:

Density in g/cm³

Solution:

We know that,

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

Given that,

Mass = 2.75 Kg

Converting Kg into g

[ multiply by 1000 ]

Since,

1 Kg = 1000 g

Hence,

⇒ Mass = 2750 g

⇒ Volume = 250 cm³

According to the Question,

We are asked to find the Density in g/cm³

Hence,

By substituting the above values in the formula,

We get,

$\sf \implies Density=\dfrac{2750}{250} \ g/cm^{3}$

On further simplification,

We get,

$\sf \implies Density=11 \ g/cm^{3}$

Therefore,

Density = 11 g/cm³
