4 kg of kerosene was poured into the can. Determine the weight of kerosene and what is its volume

4 kg of kerosene was poured into the can. Determine the weight of kerosene and what is its volume, if the density of kerosene is 800 kg / m3.

m = 4 kg.

g = 9.8 m / s2.

ρ = 800 kg / m3.

P -?

V -?

The weight of the body P is the force with which the body presses on the support or stretches the suspension. Since the can with kerosene is at rest, the weight of kerosene P is equal to the force of gravity m * g: P = m * g.

P = 4 kg * 9.8 m / s2 = 39.2 N.

The payability of a substance ρ is the ratio of the mass of a substance m to the volume V that this substance occupies: ρ = m / V.

V = m / ρ.

V = 4 kg / 800 kg / m3 = 0.005 m3.

Answer: kerosene in a can has a weight of P = 39.2 N and occupies a volume of V = 0.005 m3.
