Calculate the mass of sodium chloride (NaCl) produced when 5.50 moles of solid sodium reacts in excess chlorine gas. (Hint: Start by writing a balanced chemical equation)
Please help me understand HOW to solve this problem.
start with a balanced equation. Then, notice the ratio of moles Na to moles of NaCl.
then finally, convert the moles of NaCl to mass
where formula mass of NaCl is the atomic mass of Na plus the atomic mass of chlorine atom.
In my head, I get about 320grams of sodium chloride.
Thanks, after seeing this, I see how easy the problem actually was.
