#### Explanation:

Take a look at what information the problem provides you with.

Notice that you are given density, expressed in *grams per cubic centimeter*, and volume, expressed in *cubic centimeters*.

As you know, density is defined as mass per unit of volume

#color(blue)("densitgy" = "mass"/"volume")#

In your case, a density of **each**

Well, if

#15.00color(red)(cancel(color(black)("cm"^3))) * "2.50 g"/(1color(red)(cancel(color(black)("cm"^3)))) = color(green)("37.5 g")#
