33. A student finds that the mass of 25ml of an unknown liquid is 20.5g. What is the density of this substance?

Density,

Explanation:

It is given that,

Mass of an unknown liquid, m = 20.5 g

The volume of unknown liquid is 25 mL

We need to find the volume of the brass object. Mass per unit volume of an object is called its density.

We know that, 1 mL = 1 cm³

So, 25 mL = 25 cm³

Putting the values, we get :

So, the density of this substance is

h let me think

what is the question?
