as the title says...i need to find the pH of these solutions but do not know how


a. edit. i solved the first one but now am lost on the rest  

b. .260 M NH4NO3 and .102 M HCN

c. 7.5*10^-2 M RbOH and .110 M NaHCO3

d. .110 M NaClO and 4.5*10^-2 M KI

these are the "challenge problems" at the end of our hw...my lab partners and i  are all having trouble with them...
