### PS5.7 asks you to describe how to prepare a given amount of a solution of
a given concentration. THis type of problem is asking you to determine the amount
of solute you will need to prepare the solution, and the amount of solvent or
the amount of solution. When you write up your answer you need to show all the
calculations you have done, and then think of yourself in the storeroom preparing
the solution. How much solute must you weigh out? Then how much solvent do you
need, or what is the final volume you must mix and dilute the solution to?

### In PS5.7 I'm asking you to explain how you would prepare a solution of the
stated amount and the stated concentration. Part a of the problem is similar...identical...to
problems we did in CHEM 1314. There is an example
of this kind of calculation (PS5.7a) in our lecture notes from CHEM 1314.

### For parts b and c in PS5.7 I recommend you use the approach that is used in
PS5.5 amd PS5.6. That is to re-express the solution in terms of another concentration
term. But you have to select which concentration term is best for the particular
solution I've asked you to prepare. In the new concentration you could then
easily determine the amount of solute and solvent you need to prepare the solution.

### Hope this helps.
