| **A one-liter jar filled with olia has a mass of 1200 g, the same jar half-filled with honey has a mass of 1 kg. Find the density of honey if the density of olia is 900kg / m3.**

Data: m1 (weight of a liter can with sunflower oil) = 1200 g (1.2 kg); m2 (weight of a liter jar half filled with chalk) = 1 kg.

Reference values: according to the condition ρp.m. (density of sunflower oil) = 900 kg / m3.

1) Determine the mass of a liter can: mb = m1 – ρp.m. * V1 = 1.2 – 900 * 10-3 = 0.3 kg.

2) Calculate the mass of honey in the jar: mm = m2 – mb = 1 – 0.3 = 0.7 kg.

3) Determine the density of honey: ρm. = mm / V2 = 0.7 / (0.5 * 10-3) = 1400 kg / m3.

Answer: The density of honey in a jar is 1400 kg / m3.
