Answer:

2gcm⁻³

Explanation:

Given parameters:

Mass of the object  = 20g

Volume = 10mL

Unknown:

Density of the object  = ?

Solution:

Density of a body is its mass per unit volume;

   Density  = \frac{mass}{volume}  

We need to convert mL to cm³ for the volume

     1mL  = 1cm³;

        10mL is therefore, 10cm³  

So;

       Density  = \frac{20}{10}   = 2gcm⁻³
