What is the new concentration of acetic acid after 120mL of 0.201M acetic acid is mixed with 160mL of 0.248M sodium acetate

Question

Im not sure how to start this one would it be (120x.201)+(160x.248)

Answer 1

This makes a buffered solution; however, the problem doesn't ask for pH. I think this is nothing more than a dilution problem.
new (HAc) = 0.201 x [120/(120+160) ]= ?

Answer 2

thank you
