Problem

A cationic surfactant solution shows micellization at

1.2 \times 10^{-3}\,\mathrm{M}

. Assuming that

1\,\mathrm{mm}^3

of solution contains on an average of

2.4 \times 10^{12}

micelle particles, the number of ions present in one micelle is

3 \times 10^a

(Av. no. is

6 \times 10^{23}

). What is the value of

a
