Expert Answer

Step 1

The gas constant (R) in L atm/mol K is equal to 0.082 L atm/mol K. The mass of 0.250 kg is equivalent to 250 g and 27 0C is equivalent to 300.15 K.

Step 2

The number of moles of oxygen is calculated as shown in equation (1) where ‘n’ is the number of moles of oxygen gas, 32 g/mol is the molar mass of the O2 gas, ...
