Question

The mass of oxygen gas which occupies 5.6 liters at STP would be(a) The gram atomic mass of oxygen.(b) One fourth of the gram atomic mass of oxygern(c) Double the gram atomic mass of oxygen(d) Half of the gram atomic mass of oxygen

Answer 1

Explanation:

(a,d) 1 mole of 02 gas at STP = 6.022 x 1023 molecules of 02 (Avogadro number) = 32 g of 02. Hence, 1 mole of oxygen gas is equal to molecular weight of oxygen as well as Avogadro number.

Answer 2

Answer:

D)is the correct answer

Explanation:

gram atomic weight of oxygen is 16g as half of 16g is 8g the option D is correct
