Question

A sample of marble has a volume of 8 cm3 and a density of 2.75 g/cm3. What is its mass?

Answer 1

Using the formula Density = Mass / Volume,

Mass = Density x Volume
Mass = 2.75 x 8 = 22g

Answer 2

Answer: The correct answer is 22 g.

Explanation:

The expression for the relation between mass and density is as follows;

$Density=\frac{m}{V}$

Here, m is the mass of the object and V is the volume of the object.

It is given in the problem that A sample of marble has a volume of $8 cm^{3}$ and a density of  $2.75 \frac{g}{cm^{3}}$.

Calculate the mass of a sample marble.

$m= (Density)(V)$

Put $V=8 cm^{3}$ and $Density=2.75 \frac{g}{cm^{3}}$.

$m= (2.75)(8)$

m=22 g

Therefore, the mass of a sample of a marble is 22 g.
