Question

Calculate the amount of NaOH required to neutralize 100 mL  0.1 M H₂SO₄.

(a)  40 g

(b)  0.4 g

(c)  80 g

(d)  0.8 g

Answer 1

Correct option (d)  0.8 g

Explanation:

• 0.1 MH₂SO₄ = 1000 mL solution contains 0.1 mol H₂SO₄

:. 100 0.01 mL solution contains mol H₂SO₄ 

• :. mass of H₂SO₄  = 0.01 X 98 =  0.98 g
