In a large container in an oil refinery, three oils of different densities are mixed. No chemical activity occurs.
The mixture consists of:
1200 kg of oil of density $1100{\text{ kg }}{{\text{m}}^{ - 3}}$
1500 kg of oil of density $860{\text{ kg }}{{\text{m}}^{ - 3}}$
4000 kg of oil of density $910{\text{ kg }}{{\text{m}}^{ - 3}}$
What is the density of the mixture?
