How do you calculate the pH difference when the following substances are added to a buffer.(all of the solutions are at .10M conc.)

The buffer: 50mL NH3 + 50mL NH4NO3
1) 10mL buffer + 6mL water
2)10mL buffer + 5mL water +1mL HCl
3)10mL buffer + 6mL HCl
4)10mL buffer + 5mL water + 1mL NaOH

I'm really confused on how the equations are set up for these types of problems (buffer solns).
Thanks
