Suppose you have three NaCl solutions, of concentrations 0.1, 0.2 and 0.3

µM, and you want to use some of each solution in order to make 0.1 L of a 0.22

µM NaCl solution.

a. How much of each solution would you use?

b. How many ways can you combine your three solutions to get the desired outcome?

c. Can you make the desired solution without using any of the 0.2

µM solution?

d. Can you make the desired solution without using any of the 0.3

µM solution?
