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](https://images.topperlearning.com/topper/tinymce/cache/7baa51f1a4bbf1ed9c6ba407f99bd3bf.png)
