Final answer:

The density of motor oil is approximately 0.861 g/mL.

Step-by-step explanation:

To find the density of motor oil in g/mL, we need to use the formula:

Density = Mass / Volume

First, we need to convert the given volume of 1.25 quarts to milliliters. Since 1 quart is equal to 946.35 milliliters, we get:

Volume = 1.25 qt * 946.35 mL/qt = 1182.94 mL

Next, we need to convert the given mass of 2.25 pounds to grams. Since 1 pound is equal to 453.59 grams, we get:

Mass = 2.25 lb * 453.59 g/lb = 1019.86 g

Now we can substitute the values into the density formula:

Density = 1019.86 g / 1182.94 mL = 0.861 g/mL

Therefore, the density of motor oil is approximately 0.861 g/mL, which is not among the given answer choices.
