Given that 15.00 cm3 of H2
SO

Given that 15.00 cm3 of H2
SO4 was required to completely neutralize 25.00 cm3 of 0.125 mol dm-3 NaOH, calculate the molar concentration of the acid solution:

A.

0.925 mol dm-3

B.

0.156mol dm-3

C.

0.104 mol dm-3

D.

0.023 mol dm-3

View answer & explanation

Correct answer is C

H2SO4 + 2NaOH → Na2SO4 + 2H2O
(MaVa)/(MBVB) (1)/(2) (MA x 15)/(0.125 x25) = 1/2
MA = 0.104
