The question asks us to determine a property of a mass of oxygen given its initial volume and pressure, with the condition that the temperature remains constant. The phrasing "Determine the same volume of mass of gas and under pressure" is ambiguous.

Given the context of gas laws and the condition "temperature remaining constant," this problem most likely refers to Boyle's Law. Boyle's Law states that for a fixed mass of gas at constant temperature, the pressure ($P$) and volume ($V$) are inversely proportional, meaning their product is constant ($PV = k$).

We will interpret the question as asking for the constant value of the product $PV$ for this specific mass of oxygen under constant temperature conditions.

Step 1: Identify the given initial conditions.
Initial volume of oxygen, $
