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

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

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.......
