Question

one gallon (3785 ml) of gasoline has a mass of 2540 g. what is the density of gasoline? 1.67 g/ml 1.49 g/ml 1.00 g/ml 0.671 g/ml

Explanation:

Step1: Recall density formula

The density formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume.

Step2: Identify given values

Given $m = 2540\ g$ and $V=3785\ mL$.

Step3: Calculate density

$
ho=\frac{2540\ g}{3785\ mL}\approx0.671\ g/mL$

Answer:

0.671 g/mL
