Question 32

Mole Concept and Stoichiometry

The volume of 2.5 moles of oxygen at s.t.p. is [Molar volume of a gas at s.t.p. = 22.4 dm3]

  1. A.50.0 dm3
  2. B.84.0 dm3
  3. C.28.0 dm3
  4. D.56.0 dm3
Show the answer and explanation

Answer: D (56.0 dm3)

Explanation

Volume = moles × molar volume = 2.5 × 22.4 = 56.0 dm3.
