What is the concentration of a solute, in g/100 cubic centimeters, if one can dissolve 5.0g of the solute in 20.0 cubic centimeters of solvent?

Simple proportion:

$\frac {5.0\,g}{20\,cm^3} = \frac {x}{100\,cm^3}$

Can you figure it out from there?

There's only the math to do in your question...

Your question itself show what to do; see:

So, you can have your formula;

$Concentration = \frac{mass(g)}{volume(100cm^3)}$

Now, in 20 cm^3, you have 5.0 g

How many grams would there be in 100 cm^3? This is simple proportions.

Hope it helped! :)
