Answer:

Take a #1L# volumetric flask, and thru a funnel quantitatively transfer a #37.276*g# mass of potassium salt. Fill the flask up to volume.

Explanation:

So all you have to do is accurately weigh the potassium chloride (of course if it's a bit out, you still know the accurate concentration). Potassium chloride has a molar mass of #74.5513*g*mol^-1#; it is very (and easily) soluble in water, so you will have no difficulty in dissolving such a mass BEFORE you fill the flask to volume.
