What is the volume in dm ^3 occupied by 3 ~mol of ammonia gas at STP?

Options

  1. A2.24
  2. B22.4
  3. C56.0
  4. D67.2

Correct answer

D. 67.2

Step-by-step solution

aligned & Number of moles of a gas ( n ) & = Volume of a gas at STP Molar volume of a gas & Volume of ammonia gas at STP & = Number of moles of the gas ( n ) & Molar volume of the gas & =3 ~mol 22.4 dm ^3 ~mol ⁻¹ & =67.2 dm ^3 aligned
