Question

Find the mass of the object if it has a volume of 20 mL and a density of 3 g/mL.

Answer 1

60 g

Explanation:

Use the density formula, D = m/v, where m is the mass and v is volume

Plug in the volume and density, then solve for the mass:

D = m/v

3 = m/20

60 = m

So, the mass is 60 g

Answer 2

Given :

Volume of object = 20 mL

Density of object = 3 g/mL

To Find :

We have to find mass of the object
`.`

Solution :

★ Density is defined as the mass of object per unit volume.

It is a scar quantity having only magnitude.

Mathematically, ρ = M/V

• ρ denotes density
• M denotes mass
• V denotes volume

By substituting the values, we get

⭆ 3 = M/20

⭆ M = 3 × 20

⭆ M = 60 g

∴ Mass of the object is 60g.
