What is the density of motor oil in g/mL if 1.25 quart (qt) weighs 2.25 pounds (lb)?

0.86 g/mL

Explanation:

In order to solve the problem, you have to know the formula for "Density." Density refers to "mass per unit volume." It's formula is:

Next, we have to convert the units of measurement in accordance to what is being asked in the problem. It is asking for "g/mL," which means we have to convert 1.25 quarts (qt.) to mL and 2.25 pounds (lbs.) to grams.

Let's solve.

1.25 qt. x = 1,182.94 mL

2.25 pounds x = 1,020.58 grams

Now that we converted them to their appropriate units of measurement, we can now solve for density.

The density of the motor oil is 0.86 g/mL

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
