This problem is providing us with the mass and density of a sample of liquid magnesium as 0.015 g and 1.738 g/cm³, respectively. Thus the volume, in microliters, of this same is required and found to be 8.63 μL according to the following calculations:
<h3>Density:</h3>
In science, density is defined as the degree of compactness of a substance and is calculated with:

Thus, given both the mass and density, we can solve for the volume as shown below:

By plugging in, we obtain the answer in cm³ first:

Then, we convert it to microliters as follows:
