The capacity of the car’s gas tank is 30 liters. Determine the mass of gasoline entering the gas tank.
| March 13, 2021 | education
Initial data: V (vehicle gas tank capacity) = 30 liters.
Constants: according to the condition ρ (gasoline density) = 710 kg / m ^ 3.
SI system: V = 30 l = 30 dm ^ 3 = 30 * 10 ^ -3 m ^ 3.
The value of the mass of gasoline in a gas tank can be represented as the product of the capacity of the gas tank and the density of gasoline.
m = ρ * V = 710 * 30 * 10 ^ -3 = 21.3 kg.
Answer: The mass of gasoline in the gas tank is 21.3 kg.
