Answer:

If you have a #1500*mL# of a #0.50*mol*L^-1# solution, you have #0.75*mol# in solution........

Explanation:

#"Molarity"="Concentration"="Moles of solute"/"Volume of solution"#

And of course #"Moles of solute"="Mass of solute"/"Molar mass of solute"#......

But we don't have the molar mass of the solute, and we are guessing that a #"semi molar solution"# #=# #0.50*mol*L^-1#.

We need more data please.......
