How many moles do you want? That's moles = M x L = 1 M x 0.5 L = 0.5
How many grams is 0.5 mole? That's grams = mols x molar mass = 0.5 x 58.5 = ?
So, weigh out ? grams NaCl, place in a 500 cc volumetric flask, add some distilled water, stir until all of the NaCl is dissolved, add more distilled water to the mark on the volumetric flask, stopper, mix thoroughly, label. done.
