An automobile gasoline tank holds 25.0 gal when full. how many pounds of gasoline will it hold if the gasoline has a density of
lora16 [44]

The amount (in pounds) the gasoline tank will hold when full is 153.76 lb

<h3>What is density? </h3>

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

<h3>How to convert gallon to milliliters </h3>

1 gallon = 3785.412 mL

Therefore,

25 gallon = 25 × 3785.412

25 gallon = 94635.3 mL

<h3>How to determine the mass </h3>
  • Density = 0.737 g/mL
  • Volume = 94635.3 mL
  • Mass =?

Mass = Density × Volume

Mass = 0.737 × 94635.3

Mass = 69746.2161 g

<h3>How to convert grams to pounds </h3>

453.592 g = 1 lb

Therefore,

69746.2161 g = 69746.2161 / 453.592

69746.2161 g = 153.76 lb
