Options

  1. AThe density of a gas at 27^ ^ C and 1 atm pressure is 2.6\ g/dm^3 . What is molar mass of gas? [R = 0.0821\ L atm K^ -1
  2. BThe density of a gas at 27^ ^ C and 1 atm pressure is 2.6\ g/dm^3 . What is molar mass of gas? [R = 0.0821\ L atm K^ -1
  3. CThe density of a gas at 27^ ^ C and 1 atm pressure is 2.6\ g/dm^3 . What is molar mass of gas? [R = 0.0821\ L atm K^ -1
  4. DThe density of a gas at 27^ ^ C and 1 atm pressure is 2.6\ g/dm^3 . What is molar mass of gas? [R = 0.0821\ L atm K^ -1

Correct answer

B. The density of a gas at 27^ ^ C and 1 atm pressure is 2.6\ g/dm^3 . What is molar mass of gas? [R = 0.0821\ L atm K^ -1

Step-by-step solution

A mixture of gases O2,H2{O}_{2}, {H}_{2} and COCO are taken in a closed vessel containing charcoal The graph that represents the correct behaviour of pressure with time is given below:

A mixture of gases O _ 2 , H _ 2 and CO are taken in a closed vessel containing charcoal The graph that represents the

Due to adsorption pressure of gas will decrease with time.
