The density of the liquid at the given temperature is 1.622 g/mL
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
<h3>How to determine the density </h3>
The density of the liquid can be obtained as illustrated below:
- Mass of liquid = 40.55 g
- Volume of liquid = 25 mL
- Density of liquid =?
Density = mass / volume
Density = 40.55 / 25
Density of liquid = 1.622 g/mL
