How many moles do you start with?
M x L = 3.55 x 0.250 = 0.8875
How much do you want to add of 5.65 M? That will be 4.65 x Y L = ??
You want the total to be 4.50 M and the volume will be 0.250 L + yL so set up the equation.
(3.55 M x 0.250) + (5.65 M x YL) = 4.50 M x (0.250+Y)abd solve for Y. The total volume then will be Y + 0.250 L. I get something like 206 mL for Y (0.206 L).
M x L = 3.55 x 0.250 = 0.8875
