Answer:
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:
- Density (ρ) = [tex]\frac{mass}{Volume}[/tex]
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 [tex]\frac{946.35 mL}{1 qt.}[/tex] = 1,182.94 mL
2.25 pounds x [tex]\frac{453.592 grams}{1 pound}[/tex] = 1,020.58 grams
Now that we converted them to their appropriate units of measurement, we can now solve for density.
- ρ = [tex]\frac{mass}{Volume}[/tex]
- ρ = [tex]\frac{1,020.58 grams}{1,182.94 mL}[/tex]
The density of the motor oil is 0.86 g/mL
