If body fats has a density of 0.94 g/mL and 3.0 liters of fat are removed, how many pounds of fat were removed from the patient?

6.217 pounds

Explanation:

We are given;

Density of body fats 0.94 g/mL Volume of fats removed = 3.0 L

We are required to determine the mass of fats removed in pounds.

We need to know that;

Density = Mass : volume

1 L = 1000 mL, thus, volume is 3000 mL

Rearranging the formula;

Mass = Density * Volume

= 0.94 g/mL * 3000 mL

= 2,820 g

but, 1 pound = 453.592 g

Therefore;

Mass = 2,820 g : 453.592 g per pound

= 6.217 pounds

Thus, the amount of fats removed is 6.217 pounds
