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#
