Answer:

Volume of gas ( V ) = 19.8935 L

Explanation:

Data Given:

no. of mole of gas (n) = 21.0 mole

Pressure P = 78.0 atm

Temperature T = 900 K

Ideal gas constant = 0.08206  L atm K⁻¹ mol⁻¹

Volume of gas = ?

Formula used for Ideal gases

                                               <em> </em><em> </em>PV = nRT

As we have to find volume of the gas:

We will rearrange the ideal gas equation as below:

                                         V = nRT / P  ........................................... (1)

Put value in equation (1)

                  V =  21.0 mol x 0.08206  L atm K⁻¹ mol⁻¹ x 900K / 78.0 atm

                  V = 19.8935 L

Volume of gas V = 19.8935 L
