Question

Dada la ecuacion :pcl5+—pcl3+cl2, los gramos de cl2 que pueden obtenerse por descomposicion de 121,2g de pcl5, son:

Answer 1

Mm PCl5 =208.24 g/mol
         Cl2 = 70.90 g/mol
                                PCl5 → PCl3 + Cl2

g Cl2 = 121.2 g PCl5  x  1 mol PCl5  x  1 mol Cl2  x  70.90 g Cl2                                      ````````````````    ```````````````    `````````````````                                     208.24 g PCl5    1 mol PCl5    1 mol Cl2
g Cl2 = 41.27
