Answer:

5.4 M.

Explanation:

  • At complete neutralization: It is known that the no. of millimoles of acid equal that of the base.

(MV)acid = (MV)NaOH

M of acid = ??? M, V of acid = 35.0 mL.

M of NaOH = 3.0 M, V of NaOH = 63.0 mL.

∴ M of acid = (MV)NaOH / (V)acid = (3.0 M)(63.0 mL)/(35.0 mL) = 5.4 M.
