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)?
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."
