Calculate the molarity of a solution prepared by the addition of 2.59 g of NaNO3 into 250 ml of solution.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

lol idk man i guess u gotta ask bill nye the science guy
