In the chlor-alkali process, the mass of NaCl(s) required to produce 0.793 kg of chlorine gas is _____ kg.

  • Science -

    The process reaction is:
    2 NaCl + 2 H2O -> 2NaOH + H2 + Cl2

    Convert 793 g of Cl2 to moles. It is about 11.17 moles.

    You will need twice as many moles of NaCl. Convert that number to mass of NaCl, in the usual manner.
