You need to find the formula mass of NaCl first, which you find the amu of both sodium and chlorine on the periodic table and you add them both. Then you divide the 175.5g by the formula mass which I got 58 g to get 3.026 moles of NaCl. 4 sig figs because of the 175.5. I recommend doing it on your own to make sure you get the right answer. You divide the 175.5g of NaCl by the formula mass.
<span>The answer is 4. Molecular formulas express how many atoms of every element are in a compound, and empirical formulas express the reduced share of elements in a compound. If a compound's molecular formula cannot be made lower any longer, then the empirical formula is the similar as the molecular formula.</span>
Probably About 2 or 3 more
