ρ (rho) = density, m = mass, V = volume. The SI unit of density is kg/m3. Water of 4 °C is the reference ρ = 1000 kg/m3 = 1 kg/dm3 = 1 kg/l or 1 g/cm3 = 1 g/ml.
Also, how can you determine the density of liquid?
- 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.
