Expert Solution
Step 1

To Calculate  the new temperature we must have to use the equation of ideal gas law

                                                                       PV = n RT

we have given two cases

case- I              pressure of oxygen gas (P1) = 1.2atm

                        volume of oxygen gas (V1)  = 2.3L

                        no of mole of oxygen gas (n1)= 5 mole

                        temperature of oxygen gas (T1) = 315 K

 

Case - II      pressure of oxygen gas(P2) = 3.4atm

                   volume of oxygen gas (V2) =6.1L

                   no of mole of oxygen gas (n2) = 7 mole

                  temperature of oxygen gas (T2) = 'X' K
