I have some chemistry questions. please get all the answers correct ;)

a) Calculate the standard cell potential for the following cell

Zn (s) | Zn2+ (aq) (1M) || Co2+ (aq) (1M) | Co (s)

answer = __________V

b) The following cell was constructed and found to produce a voltage of 1.08 V.

Co (s) | Co2+ (aq) (1M) || Ag+ (aq) (1M) | Ag (s)

Calculate the standard reduction potential for Ag+ (aq) | Ag (s)

answer = _______V

c) Which of these species is the best oxidising agent?
