How many mols do you want? That's mols \ M x L = ?
Then mols = grams/molar mass. You know molar mass NaNO3 and mols, solve for grams.
Then place that many g NaNO3 in a 500 mL volumetric flask, add some water, swirl until all of the NaNO3 is dissolved, add DI water to the mark, stopper, mix thoroughly.
describe how you would prepare 500mL of 0.25 M NaNO3 solution?
