Expert Answer
Molality = 0.02 m 
Dissociation of NaCl is written as-
straight i equals 2 increment straight T subscript straight b space equals straight i cross times straight m cross times straight K subscript straight b fraction numerator increment straight T subscript straight b over denominator straight K subscript straight b end fraction equals straight i cross times straight m equals 2 cross times 0.02 equals 0.04 space straight m
