Solution
The balanced chemical equation for the reaction is,
I2+2Cl2→ICl+ICl3
Thus, 1 mole of iodine reacts with 2 moles of chlorine to form 1 mole of iodine trichloride.
The molar masses of iodine and chlorine are 254g/mol and 71g/mol respectively.
254 g of iodine corresponds to 1 mole and 142 g of chlorine corresponds to 2 moles. 1 mole of iodine requires 2 moles of chlorine. Hence iodine and chlorine are present in stoichiometric amount. Thus, 1 mole of iodine trichloride is formed.
