<u>Answer:</u> The volume of oxygen gas is 
<u>Explanation:</u>
To calculate the volume of the gas, we use the equation given by ideal gas equation:

where,
P = pressure of the gas = 5 MPa = 5000 kPa (Conversion factor: 1 MPa = 1000 kPa)
V = Volume of gas = 3.34 L
n = number of moles of oxygen gas = 1 mole
R = Gas constant = 
T = Temperature of the gas = 200 K
Putting values in above equation, we get:

Hence, the volume of oxygen gas is
