3. A 25.0-mL sample of concentrated sulfuric acid, H2SO4, is diluted to 1.00 L and a 25.0-mL sample of the dilute acid is further diluted to 100. mL. Then a 10.0-mL sample of the latest solution is titrated with 0.1075 M NaOH. If 20.8 mL of the NaOH solution is required to neutralize the very dilute H2SO4 solution, what is the concentration of H2SO4 in the original concentrated acid? (A) 4.47 M (B) 8.94 M (C) 17.9 M (D) 23.2 M

3. A 25.0-mL sample of concentrated sulfuric acid, H2SO4, is diluted to 1.00 L and a 25.0-mL sample of the dilute acid is further
diluted to 100. mL. Then a 10.0-mL sample of the latest solution is titrated with 0.1075 M NAOH. If 20.8 mL of the NaOH
solution is required to neutralize the very dilute H2SO4 solution, what is the concentration of H2SO4 in the original
concentrated acid?
(A) 4.47 M
(В) 8.94 М
(C) 17.9 M
(D) 23.2 M
