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.

    MolesNaCl=Ratio*molesNa

    then finally, convert the moles of NaCl to mass
    MassNaCl=MolesNaCl*formulamassNaCl

    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.
