What is the volume (in dm ^3 ) occupied by 75 ~g ethane at S.T.P.?

Options

  1. A60.0
  2. B56.0
  3. C22.4
  4. D44.8

Correct answer

B. 56.0

Step-by-step solution

Number of moles of ethane ( C ₂ H ₆ )= 75 30 =2.5 Volume of gas at S.T.P = moles 22.4 ~L aligned & =2.5 22.4 & =56 ~L & =56 dm ^3 & (1 ~L =1 dm ^3 ) aligned
