Question

Q.52 A sample of 100cm*3of dilute H2SO4 contains 0.1 moles of acid. What is hydrogen ion concentration in the solution per dm3 A. 2 moles B. 0.50 moles C. 0.25 moles D. 1 mole​

Answer 1

Answer: (A) 2 moles

Explanation:

1 dm³ = (10 cm)³ = 1000 cm³

Moles of acid in 1000 cm³ dilute H₂SO₄ = 0.1×1000/100 = 1

Since every molecule of H₂SO₄ contains 2 hydrogen ions,

Moles of hydrogen ions per 1000 cm³ = 1×2 = 2

Hope it helped
