The half life is the time required for the concentration to drop to one-half its original value. 2 minutes is 2*60= 120 sec.
If you have 120 sec and time of half life, you can calculate number of concentration decreasing to one-half of its previous value.
120 sec / 32 sec = 3.75 and it means that you need divide original concentration on 2 3.75 times to get 0.062 M, so
[C]/2^3.75 = 0.062 M
[C]/13.45 = 0.062 M
[C] = 0.062 M*13.75
[C] = 0.8525 M
