A sample of motor oil has a mass of 440 g and a volume of 0.27 L. What is its
density (in g/mL)?

Explanation:

The density of a substance can be found by using the formula

To find the density in g/mL , we must first convert the volume from L to mL

From the question

mass = 440 g

1 L = 1000 mL

0.27 L = 0.27 × 1000 = 270 mL

volume = 270 mL

Substitute the values into the above formula and solve for the Density

That's

= 1.629629...

We have the final answer as
