Question
describe how you would prepare 500mL of 0.25 M NaNO3 solution?

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.
