# If the density of a sample is 14 g/mL, and its mass is 56 grams, what would its volume be?

##### 1 Answer

#### Explanation:

The idea here is that the **density** of a substance can be thought of as being a *conversion factor* between the **mass** of a sample of this substance and the **volume** it occupies.

In your case, the sample is said to have a density of

In other words, **for every** milliliter of that substance that you have in your sample, you get a mass of

The problem tells you that the mass of the sample is equal to *more than*

*How much more?*

Use the given density to find out!

#56 color(red)(cancel(color(black)("g"))) * overbrace("1 mL"/(14color(red)(cancel(color(black)("g")))))^(color(purple)("density as a conversion factor")) = color(green)(|bar(ul(color(white)(a/a)"4.0 mL"color(white)(a/a)|)))#
