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 13.4 gal tank?

Question

agent_a · Answer

This is what I did but it was wrong:

$$Density = \frac{ mass }{ volume }$$

$$13.4 gal * 3.79 = 50.786 \frac{ L }{ gal }$$

50.786 $$(50.786 \frac{ L }{ gal })(\frac{ 10^{-3} mL}{ 1L }) = 0.050786 \frac{ mL}{ gal }$$

$$(0.737 \frac{ g }{ mL })(0.050786 \frac{ mL }{ gal }) = 0.037429282 \frac{ g }{ gal }$$

How do I take the "gal" out of the units of my final answer?
