Question

Can someone help me solve these? I do not really understand how to calculate pH and how the varying mL concentrations would be calculated/impact the final product(s). Thank you. 

The buffer in this experiment is made of acetic acid HC2H3O2 and sodium acetate NaC2H3O2 (C2H3O2 ).
Ka = 1.76 x 10-5 for HC2H3O2
What is the pH of this solution?

solution
А
acetic acid, 0.1 M (mL)
sodium acetate, O.1 M (mL)
distilled water (mL)
After 1 mL of 0.1M HCI is added to this solution, what is the
pH?
