PLEASE HELP ME WITH THIS QUESTION I don’t really understand and I need help :/

0.09 moles of sodium sulfate in 12 ml of solution

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.

Which three statements represent the benefits of performing experiments using computer simulations?
