Calculate the volume of 0.320-M NaOH solution needed to completely neutralize 74.0 mL of a 0.230-M solution of the monoprotic acid HBr. mL NaOH.

Respuesta :

Answer:

53.2 mL

Explanation:

As this problem deals with the neutralization of a strong monoprotic acid and a strong base, we can solve it by using the following formula:

  • Ca * Va = Cb * Vb

Where in this case:

  • Ca = 0.230 M
  • Va = 74.0 mL
  • Cb = 0.320 M
  • Vb = ?

We input the data:

  • 0.230 M * 74.0 mL = 0.320 M * Vb

And solve for Vb:

  • Vb = 53.2 mL
