What is the quantity of hydrogen gas liberated when 46 g sodium reacts with excess ethanol? (Given Atomic mass of Na = 23)

Options

  1. A2.4 × 10 - 3 k g
  2. B2.0 × 10 - 3 k g
  3. C4.0 × 10 - 3 k g
  4. D2.4 × 10 - 2 k g

Correct answer

B. 2.0 × 10 - 3 k g

Step-by-step solution

1 mole of H 2 = 2 g of H 2 ≡ 2 × 10 - 3 k g
