At 300 ~K , 22 ~g of CO ₂ gas exerts a pressure of 5 atmosphere. What is volume of the gas at same temperature? ( R =0.0821 ~L ~atm ~K ⁻¹ ~mol ⁻¹ )

Options

A5.61 dm ^3
B8.20 dm ^3
C2.46 dm ^3
D3.80 dm ^3

Correct answer

C. 2.46 dm ^3

Step-by-step solution

aligned & P _ CO ₂ =5 ~atm & ~T =300 ~K aligned Moles of gas = 22 44 ( . Molar mass of CO ₂ is 44 ) aligned & =0.5 & PV = nRT & V = nRT P = 0.5 0.0821 300 5 & =2.46 dm ^3 aligned
