All right. So here we're trying to find the molar mass of table salt sodium chloride. So here we would take a look at our periodic table and we would take a look at the, uh, weighted average mass of each element sodium and quarry. Let's write those down. So sodium is 22.990 grams per mole and chlorine, 35 points 45 three grams per mole. So since there's only one sodium atom and one chlorine atom per molecule of sodium chloride, you just add these two numbers together in the amount shown. So something those two we get 58 point for for three grants promote, and that's the mother massive sodium chloride.
