Gasoline has a density of 0.749 g/mL. There are 454 grams in a pound and 3.7854 litres in a gallon. How many pounds does 19.2 gallons of gasoline weigh? Do not enter "pounds" as part of your answer.

119.9 pound

Explanation:

Given dа ta:

Density of gasoline = 0.749 g/mL

Volume of gasoline = 19.2 gal (19.2 * 37854 = 72679.9 mL)

Mass = ?

Solution:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL, kg/L

Formula:

D=m/v

D = density

m=mass

V=volume

Now we will put the values in formula:

d = m/v

0.749 g/mL = m / 72679.9 mL

m = 54437.25 g

gram to gallon:

54437.25 / 454

m = 119.9 pound
