Explanation / Answer

Part C

The balanced chemical equation for the reaction is

P4 (s) + 10 Cl2 (g) ----------> 4 PCl5 (g)

As per the stoichiometric equation,

10 moles Cl2 = 4 moles PCl5.

Molar mass of Cl2 = (2*35.453) g/mol = 70.906 g/mol.

Mole(s) of Cl2 corresponding to 58.0 g Cl2 = (58.0 g)/(70.906 g/mol) = 0.81798 mole.

Mole(s) of PCl5 produced = (0.81798 mole Cl2)*(4 moles PCl5/10 moles Cl2) = 0.327192 mole 0.327 mole (ans).

Part D

Molar mass of PCl5 = (1*30.973 + 5*35.453) g/mol = 208.238 g/mol.

Mass of PCl5 corresponding to 0.327 mole = (0.327 mole)*(208.238 g/mol) = 68.0938 g 68.094 g (ans).
