The mass of oxygen gas which occupies 5.6 ~L at STP would be

Options

  1. Athe gram atomic mass of oxygen
  2. Bone-fourth of the gram atomic mass of oxygen
  3. Cdouble the gram atomic mass of oxygen
  4. Dhalf of the gram atomic mass of oxygen

Correct answer

D. half of the gram atomic mass of oxygen

Step-by-step solution

Mass of oxygen in 22.4 ~L at STP =32 ~g Mass of oxygen in 5.6 ~L at STP = 32 22.4 5.6=8 ~g = 1 2 gram atomic mass of oxygen Therefore, mass of oxygen gas in 5.6 L at STP would be the half of the gram atomic mass of oxygen.
