Answer:

  • 1.12 liters

Explanation:

Calculating number of moles

  • Molar mass of O₂ = 32 g
  • n = Given weight / Molar mass
  • n = 1.6/32
  • n = 0.05 moles

At STP

  • One mole of O₂ occupies 22.4 L
  • Therefore, 0.05 moles will occupy :
  • 22.4 L x 0.05 = 1.12 L

1mol of any gas at STP contains 22.4L

moles of O_2

  • Given mass/molar mass
  • 1.6/32
  • 0.05mol

Now

Volume of O_2:-

  • 0.05(22.4)
  • 1.120L

Option D
