In Chemistry class, Samantha finds that she can make a certain solution by mixing $.04$ liters of chemical A with $.02$ liters of water (this gives her $.06$ liters of the solution). She wants to make a total of $.48$ liters of this new solution.  To do so, how many liters of water will she use?</s>.

To find out how much water Samantha needs, I need to figure out what fraction of the solution is water. I can use the ratio of water to solution that she already has: $.02$ liters of water for $.06$ liters of solution. This means that the fraction of water in the solution is $\frac{0.02}{0.06} = \frac{1}{3}$. So, one-third of the solution is water. Now, if she wants to make $.48$ liters of solution, I can multiply that by the fraction of water to get the amount of water she needs. So, the amount of water she needs is $\frac{1}{3} \times 0.48 = 0.16$ liters.
