A 0.210 mL sample of very-low-density lipoprotein (VLDL) has a mass of 206 mg. What is the density of the VLDL?

0.980 g/mL

Explanation:

We know that the density of an object can be measured by dividing its mass (g) to its volume (mL).

Formula

D=m/v

Given dа ta:

Mass = 206 mg

Volume = 0.210 mL

First of all we will convert the mg into gram.

206 mg = 0.206 g

because one gram contain thousand miligrams.

Now we will put the values in formula:

D = 0.206 g / 0.210 mL = 0.98 g/mL

So the density of VLDL is 0.98 g/mL.
