2Na + Cl2 ⇒ 2NaCl 96.6g Na ((1 mole Na)/(22.99 g Na))((1 mole Cl2)/(2 mole Na))((70.9 g Cl2)/(1 mole Cl2))=149 g Cl2

Chemical equation: [latex]2 Na + Cl _{2} -\ \textgreater \ 2NaCl[/latex] M ( Na ) = 23 g/moles   ( 2 moles Na = 46 g ) M ( Cl 2 ) = 71 g/moles  ( 1 mole Cl 2 = 71 g ) so Na needs more Cl 2 to react; 96  : x = 46 : 71 46 x = 6816 x = 6816 : 46 x = 148.17 g Answer: the mass of chlorine gas is 148.17 g.
