A particular brand of gasoline has a density of 0.737 g/mL at 25 ∘C. How many grams of this gasoline would fill a 15.3 gal tank (1US gal=3.78L)?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

Express your answer to three significant figures and include the appropriate units.
1) I converted 15.3 gal to L
15.3 gal (3.78 L/ 1 gal) = 57.834 L
2) I converted 57.834 L to mL
57.834 L (10^3 mL/1 L) = 57834 mL
3) I multiplied the density times the volume to get the mass
0.737 g/mL x 57834 mL = 42623.658 grams
4) Lastly I rounded my final answer to 3 sig figs
ANSWER: Mass = 426 grams
Pearson says I'm wrong. What did I do I wrong? Please, help. Thanks!
"Incorrect; Try Again; 5 attempts remaining
Check your conversion from liters to milliliters.
You may need to review Conversion Between L and mL."
