ρ (rho) = density, m = mass, V = volume. The SI unit of density is kg/m

^{3}. Water of 4 °C is the reference ρ = 1000 kg/m^{3}= 1 kg/dm^{3}= 1 kg/l or**1 g/cm**= 1 g/ml.^{3}Also, how can you determine the density of liquid?

**Procedure**

- Find the mass of an empty graduated cylinder.
- Pour 100 mL of water into the graduated cylinder.
- Weigh the graduated cylinder with the water in it.
- Find the mass of only the water by subtracting the mass of the empty graduated cylinder.
- Use the mass and volume of the water to calculate density.

What is the formula for density?

**Density**is the mass per unit volume. This means that the

**density**of any solid, liquid or gas can be found by dividing its mass in kilograms by its volume in cubic metres.

**Density**can be found using the

**equation**: The unit for

**density**is kg m.
