Question

Air has a density of 1.3 kg/m³. Calculate the mass of 36 m³ of air in kilograms. Give your answer to 1 decimal place.

Answer 1

Explanation:

d= 1.3 kg/m^3

volume = 36 m^3

mass = ?

we know,

$density = \frac{mass}{volume} \\ \\1.3 = \frac{mass}{36} \\ \\ mass = 46 .8 \: kg$

Answer 2

$\Large\underline\mathfrak{Question}$

Air has a density of 1.3 kg/m³. Calculate the mass of 36 m³ of air in kilograms. Give your answer to 1 decimal place.

$\rule{200}{4}$

$\bold{\boxed{\large{\boxed{\orange{\small{\boxed{\large{\red{\bold{\:ANSWER}}}}}}}}}}$

Given,

Density of the air = 1.3 kg/m³

We Need to find,

Mass of the air = ?,

If Air has volume = 36 m³

$\rule{200}{4}$

$\Large\bold\star\underline{\underline\textbf{Formula\:}}$

$\rule{200}{4}$

Here,

Density and volume of the air are provided with the que.

So , we can easily find the Mass of the air by using formula,

Density = Mass / Volume

Mass = Density x volume

Mass = 1.3 x 36 ( kg x m³/m³)

Mass = 46.8 kg

So, Mass of the air is 46.8 kilograms.

$\rule{200}{4}$

For decimals,

Mass = 47.0 kg (Approx)

Or 46.8 is correct answer.
