Question

Tracie measured 87.47 mg of cholesterol in 0.03 mL of blood. What is the density of this mixture in g/mL?

Answer 1

We can use a simple equation to solve this problem.

d = m/v

Where d is the density, m is the mass and v is the volume.

d = ?

m = 87.47 mg = 87.47 x 10⁻³ g

v = 0.03 mL

By applying the equation,

  d = 87.47 x 10⁻³ g / 0.03 mL

  d = 2.92 g/mL

Hence, the density of the mixture is 2.92 g/mL.
