Answer to Question #93704 in General Chemistry for Megan Cox

Question

A fuel tank holds 22.3 gallons of gasoline. If the density of gasoline is 0.8206 g/mL, what is the mass in kilograms of gasoline in a full tank?

Answer 1

Since

$Density = Mass/Volume$

1 Gallon = 3.785 L = 3785 ml

22 Gallons = 3.785 * 22 = 83.27 L = 83270 ml

Density = 0.8206 g/ml

0.8206 = m/83270

m = 68331.36 g = 68.33 Kg
