If you are THAT	bored and finding nothing to do, do the same for the 
following other cases as well cause she's going to need them :-)

1- She's asked for preparation of a solution in units of mole percent 
_solution_ this time (in my last post she was asked in units of mole 
percent _solvent_) and the lab, like before, has the material in units 
of volume percent solvent.

2- She's asked for preparation of a solution in units of mole percent 
solvent (like in last post) but lab only has them in volume percent 
_solution_ not solvent like in the last post).

3- She's asked for preparation of a solution in units of mole percent 
solution, but the lab happens to have everything in units of weight 
percent solution.

4- She's asked for preparation of a solution in units of mole percent 
solution, but the lab happens to have everything in units of weight 
percent solvent.

5- She's asked for preparation of a solution in units of mole percent 
solution, but the lab happens to have everything in units of weight per 
100 ml solvent.

6- She's asked for preparation of a solution in units of mole percent 
solution, but the lab happens to have everything in units of weight per 
100 ml solution.

7- She's asked for preparation of a solution in units of mole percent 
solvent, but the lab happens to have everything in units of weight 
percent solution.

8- She's asked for preparation of a solution in units of mole percent 
solvent, but the lab happens to have everything in units of weight 
percent solvent.

9- She's asked for preparation of a solution in units of mole percent 
solvent, but the lab happens to have everything in units of weight per 
100 ml solvent.

10- She's asked for preparation of a solution in units of mole percent 
solvent, but the lab happens to have everything in units of weight per 
100 ml solution.

11- She's asked for preparation of a solution in units of weight percent 
solvent, but the lab happens to have everything in units of weight per 
100 ml solution.

12- She's asked for preparation of a solution in units of weight percent 
solution, but the lab happens to have everything in units of weight per 
100 ml solvent.

13. She's asked for preparation of a solution in units of weight percent 
solution, but the lab happens to have everything in units of mole 
percent solvent.

14. She's asked for preparation of a solution in units of weight percent 
solvent, but the lab happens to have everything in units of mole percent 
solvent.

And so on and so on...

Welcome to a physics forum Starmaker! See not everything can be gone 
over, or done, as carelessly as speaking about Bogart or Einstein or 
Black Holes. Sometimes one has to get his wits together and carefully 
watch everything one's doing.
