PH and PKA., Chemistry

Assignment Help:
a solid weak acid i weighed, dissolved in water and diluted to exactly 50ml. 25ml of the solution is taken out and is tittrated to a natural endpoin with .10M NaOH. The titrated portion is then mixed with the remaining untitrated portion and the PH of the mix is measured
mass of acid in grams is .629
volume of naoh required to reach endpoin in ml 18.3
ph 3.12

what is the pkaof the acid
what is the molarity of the original acid solution
what is the molecular weight of the acid
