31.0mL sample of LiOH, concentration unknown, is titrated with .52 M HCl. It takes 42.9 ml of HCl to reach the endpoint. What is the concentration of the base?

mL acid x M acid = mL base x M base.
0.71 M
I don't think you rounded properly. My calculator tells me 0.71961 which I would round to 0.72 to 2 s.f. and to 0.720 to 3 s.f.
ok thanks!
