Sodium reacts with chlorine according to the equation 2Na+Cl2→2NaCl2\mathrm{Na} + \mathrm{Cl_{2}} \rightarrow 2\mathrm{NaCl}2Na+Cl2→2NaCl. A mixture contains 4.6 g of sodium and 14.2 g of chlorine. The relative atomic masses are shown in the table.
| Element | Relative atomic mass |
|---|---|
| Sodium | 23 |
| Chlorine | 35.5 |
