Answer:
6.3moles
Step-by-step explanation:
The balanced chemical equation for the decomposition of phosphorus oxychloride (POCl3) is as follows:
POCl3 → POCl + Cl2
Based on the above decomposition reaction, it shows that;
1 mol of POCl3 will decompose to give 1 mole of Cl2
Hence, 6.3 moles of POCI3 will give 6.3 moles of Cl2.
