Question

If 25 cm' of a quantity of marbles has a mass of 45 g, calculate the density of the marble in kg/m​

Answer 1

The density of the marble will be "0.18 kg/m³".

According to the question,

Volume of marbles,

• V = 25 cm³

By converting it into m, we get

• 0.25 m³

Mass,

• M = 45 g

By converting it into kg, we get

• 0.045 kg

As we know, the formula:

→ $Density = \frac{Mass}{Volume}$

By substituting the values, we get

→               $= \frac{0.045}{0.25}$

→               $= 0.18 \ kg/m^3$  

Thus the answer above is correct.
