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)

• Chemistry -

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.

Thanks, after seeing this, I see how easy the problem actually was.
