Question

Calculate the mass, in kilograms, of an object that occupies 0.253 dm3 and has a density of 4.14 g/cm3.

Answer 1

Answer:

m = 1.047 kg

Explanation:

Volume occupied by the object, V = 0.253 dm³

1 dm³ = 1000 cm³

0.253 dm³ = 253 cm³

Density of the object, d = 4.14 g/cm³

We need to find the mass of the object. Mass per unit volume is called density of an object.

$d=\dfrac{m}{V}\\\\m=d\times V\\\\m=4.14 \ g/cm^3\times 253\ cm^3\\\\m=1047.42\ g$

or

m = 1.047 kg

So, the mass of the object is 1.047 kg.
