Buffers

A student dissolves 10.86 g of crystalline sodium acetate trihydrate (CH3COONa•3H2O) in a little water, adds 4.00 g of glacial (100%) acetic acid, and then distilled water to
make the total volume 500 mL. Calculate the molar concentration of the buffer and its pH.

My work so far
So for the trihydrate: moles = 0.092776mol
Acetic acid - 0.066608mol
volume = 500mL

But now I don't know what to do. :( Any pointers?
