Question #14959

A barrel holds 750 pounds of gasoline. The same barrel holds 1100 pounds of water when full. What is the density of gasoline? [Hint : when volume is constant, d ~ m]

Expert's answer

When the volume is constant, density is proportional to mass: d ~ m.

Set up a

proportion:

750 pounds of gasoline - x

1100 pounds of water - 1

g/cm^3

Then from the proportion we can get the unknown value x:

x =

(750 * 1) / 1100 = 0.6818 g/cm^3

Thus, the density of gasoline is 0.6818 gram

per cubic centimeter.
