Answer:
Volume of acid Va = 38.70cm3,
Concentration of acid Ca = 1.90M
Volume of Base Vb = 10.30cm3
Concentration of base Cb = ?
Equation of the reaction
H2SO4 + 2NaOH = Na2SO4 + 2H2O
No of mole of acid Na = 1
No of mole of base Nb = 2
CaVa/CbVb = Na/Nb
Cb = CaVaNb/VbNa
Cb = 1.9*38.7*2/10.30*1
Cb = 14.2777M
Explanation:
Answer: 3.57M
