Question 21

Mole Concept and Stoichiometry

During a titration experiment, 0.05 moles of carbon(IV) oxide is liberated. What is the volume of gas liberated? [Molar volume of a gas at s.t.p. = 22.4 dm3]

  1. A.22.40 dm3
  2. B.11.20 dm3
  3. C.2.24 dm3
  4. D.1.12 dm3
Show the answer and explanation

Answer: D (1.12 dm3)

Explanation

Volume = 0.05 × 22.4 = 1.12 dm3.
