Question

The density of gasoline is 0.65 g/mL. What is the mass in pounds of 45.0L (about 12 gallons) of gasoline? How would I set up this problem?? Thank you!

Answer 1

\[\rho = \frac MV\]
so \[V\rho = M\]
(\(\rho\) means density )

so... \[M = 0.65 g/mL \times 45.0 L \implies \boxed{0.65 g/mL \times 45,000 mL}\]
does that help?
