First, you cannot dissolve graduated cylinders; you dissolve 7.46 g of KCl in water IN the graduated cylinder. If you note, the molar mass is 10x the mass of KCl you use, so IF you dissolved this in 1 Liter of water, the conc would be 0.10 M. Since you used 1/40th that volume, the concentration is 40 times more or 4 molar.
BTW: concentration is spelled this way.

you dont have enough information...what was the original concentrations of the kcl?...also is it 7.46 ml ?...the formula u use to solve this is M1V1=M2V2
