Answer:

Density,
$d=0.82\ g/cm^3$

Step-by-step explanation:

It is given that,

Mass of unknown liquid is 20.5 kg

Volume, V = 25 mL

We know that, 1 mL = 1 cm³

25 mL = 25 cm³

The density of the substance is equal to its mass per unit volume. So,

$d=(m)/(V)\\\\d=(20.5\ g)/(25\ cm^3)\\\\d=0.82\ g/cm^3$

So, the density of this substance is
$0.82\ g/cm^3$ .
