Find number of moles of chlorine from ideal gas law: n(Cl2) = PV/RT = (1.2 atm)(0.56 L) / [(0.08206 L atm/mol K)(290K)] = 0.02824 mole Cl2. Balanced reaction: 2 Na + Cl2 --> 2 NaCl. Compare yields:
(0.02824 mole Cl2) * (2 mole NaCl / 1 mole Cl2) = 0.565 mole NaCl from Cl2.
(2.3g Na) * (1 mole Na /22.99g Na) * (2 mole NaCl / 2 mole Na) = 0.100 mole NaCl from Na.
The largest mass of NaCl that can be produced is limited by Cl2 gas: (0.565 mole NaCl) * (58.44g NaCl / 1 mole NaCl) = 33. g NaCl.
