The capacity of the car’s gas tank is 40 liters, the density of gasoline is 710 kg. What is the mass of the mass of gasoline, half filling the tank.
The density of gasoline is the ratio of its mass to its volume. Let’s write down the mass of gasoline:
m = p * V;
V = 40/2 = 20 HP
To solve the problem, it is necessary to express the volume in m ^ 3.
1 l = 0.001 m ^ 3, which means 20 l = 0.02 m ^ 3.
m = 710 * 0.02 = 14.2 kg.
Answer: the mass of gasoline is 14.2 kg.
