Conc = moles / Vol you have C but need to find moles 
moles KCl = mass / molar mass 
25 g / 74.55 g,p; 
0.335 moles 
So rearrange the formula to find volume. Vol = moles / Conc 
0.335 moles / 0.750 mol / L = 0.447 L or 447 mL

The answer in this question is 447 mL.

First, we determine the number of moles of KCl which has a molar mass of 74.55 g/mol.

          n = (25 g KCl)(1 mol/ 74.55 g KCl) = 500/1491 mol

Then, divide the number of calculated number of moles by the given molarity. 

            V = (500 / 1491 mol) / (0.750 mol/L)

              V = 0.447 L

Answer: 0.447 L of solution
