The density of oxygen gas at (5 ~atm ) and (127^ C ) will be
Options
- A(2.80 ~g / L )
- B(4.88 ~g / L )
- C(1.49 ~g / L )
- D(5.60 ~g / L )
Correct answer
B. (4.88 ~g / L )
Step-by-step solution
Density of a gas, ( aligned d & = p M R T [ p & = pressure =5 ~atm M & = molar mass of O ₂ gas =32 ~g ~mol ⁻¹ R & =0.082 ~L atm mol ⁻¹ ~K ⁻¹ T & =400 ~K ] & = 5 32 0.082 (273+127) & =4.878 4.88 gL ⁻¹ aligned )
