How the mass of the fuel tank changed when 75 liters of gasoline was poured into it. With a gasoline length of 710 m3.

Initial data: V (the volume of gasoline that was poured into the tank) = 75 liters.

Reference data: according to the condition ρ (gasoline density) = 710 kg / m ^ 3.

SI system: V = 75 l = 75 dm ^ 3 = 75 * 10 ^ -3 m ^ 3.

We calculate the change in the mass of the fuel tank by the formula: m = ρ * V.

Let’s calculate: m = 710 * 75 * 10 ^ -3 = 53.25 kg = 53 kg 250 g.

Answer: The mass of the fuel tank has increased by 53 kg 250 g.
