is it? M1V1=M2V2?
The solution you want contains
750 x 0.327 mmoles of NaCl
if the volume you add is x ml then the number of mmoles added is
9.54x mmoles = 750 x 0.327 mmoles
hence find x
the final volume is x+y=750 ml, where y is the volume of water added.
Two points....
9.54M NaCl would contain
9.54 x (23+35.5) g NaCl L^-1
9.54 x 58.4 g L^-1 = 557 g L^-1
as the max solubility of NaCl in water is 391 g L^-1, the question is not possible.
Also please remember to include the leading zero with decimals, so 0.327 M rather than .327 M, because the . can be easily missed.
