Two identical barrels are filled with fuel: one with kerosene, the other with gasoline. What mass of fuel is more?
| May 10, 2021 | education
V1 = V2 = V is the volume of gasoline and kerosene;
p1 = 750 kg / m ^ 3 is the density of gasoline;
p2 = 800 kg / m ^ 3 is the density of kerosene.
It is required to find the ratio m2 / m1.
m2 / m1 = V2 * p2 / V1 * p1 = p2 / p1 = 800/750 = 1.07.
Answer: the mass of kerosene is 1.07 times more.
This rule also applies to other cases – if the volume is the same, then the greater the density of the substance, the greater its mass.
