Find the volume of glass from which the jar is made, if the mass of this jar with kerosene is 1 kilogram, and the capacity of the jar is 1 liter.
m = 1 kg.
Vk = 1 l = 0.001 m ^ 3.
ρк = 800 kg / m ^ 3.
ρс = 2200 kg / m ^ 3.
Vс -?
mk = ρk * Vk.
mc = m – mk = m – ρk * Vk.
Vс = mс / ρс = (m – ρк * Vк) / ρс.
Vs = (1 kg – 0.001 m ^ 3 * 800 kg / m ^ 3) / 2200 kg / m ^ 3 = 0.00009 m ^ 3.
Answer: Vc = 0.00009 m ^ 3.
