A solution of 0.2152M NaOH is used to neutralize 15.00mL H2SO4
solution.
H2SO4(aq) + 2NaOH(aq) ?
Na2SO4(aq) + 2H2O(l)
If 32.59mL NaOH solution is required to reach the endpoint, what is the molarity of the H2SO4 solution?
H2SO4(aq) + 2NaOH(aq) ? Na2SO4(aq) + 2H2O(l)

M1 = M2 =0.2152M
V1 = 15ml V2 =32.59 ml

M1 = M2V2n1/n2V1
= 0.2152*32.59*1/2*15 = 0.2337M
