What is the molarity of a NaOH solution if 39.1 mL of a 0.220 M [tex]H_2SO_4[/tex] solution is required to neutralize a 25.0 mL sample of the NaOH solution?

A) 0.273
B) 0.355
C) 42.6
D) 0.136
E) 0.710

Answer :

The molarity of a NaOH solution can be determined using the formula M1V1 = M2V2. By substituting the given values, the molarity of the NaOH solution is found to be 0.355 M. The correct option is B

The molarity of the NaOH solution can be calculated using the formula:

Moles of H2SO4 = Moles of NaOH

M1V1 = M2V2

Substitute the given values to find the molarity of NaOH, which is 0.355 M.
