# Question #d2b20

##### 1 Answer

#### Explanation:

Yes, *weight by volume*, *mass by volume*,

The important thing to remember when dealing with either one is that you're always working with **mass**, so even if you have weight by volume, you're still going to use mass, as opposed to weight.

So, a solution's *mass by volume percent concentration* is defined as the mass of solute present in

This means that in order to find your solution's

To do that, use the known composition as a **conversion factor**

#100 color(red)(cancel(color(black)("mL solution"))) * "8.00 g dextrose"/(275 color(red)(cancel(color(black)("mL solution")))) = "2.91 g dextrose"#

This means that the solution's mass by volume percent concentration will be

#color(darkgreen)(ul(color(black)("% m/v " = " 2.91% dextrose")))#

The answer is rounded to three **sig figs**.
