Question

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

0.34 g
2.9 g
10.75 g
22 g

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.

Step-by-step explanation:

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

`Density=(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 (g)/(cm^(3))`.

Calculate the mass of a sample marble.

`m= (Density)(V)`

Put
`V=8 cm^(3)` and
`Density=2.75 (g)/(cm^(3))`.

`m= (2.75)(8)`

m=22 g

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