27.6 grams

Explanation:

That depends on the reaction. For the sake of simplicity I'll assume a single replacement reaction in the form 2"NaI" + "X"_2 rarr 2"NaX" + "I"_2 where X represents bromine, chlorine, or fluorine.

Knowing that the molar mass of "I"_2 is 253.8"g/mol" and that the molar mass of "NaI" is 149.9"g/mol",

46.7"g I"_2 xx (1"mol I"_2)/(253.8"g I"_2) xx (1"mol NaI")/(1"mol I"_2) xx (149.9"g NaI")/(1"mol NaI")=27.6"g NaI"

Edit: "X" is likely "Cl" since the reaction of "NaI" and "Cl"_2 is often used in the production of "I"_2
