To calculate the mass of oxygen in the container, we can use the ideal gas law equation PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin. First, we need to convert the given values to the appropriate units: pressure in atm (1 atm = 760 torr, so 995 torr = 995/760 atm), and temperature in Kelvin (T = 33.0 + 273.15). Then, we solve for n (moles of gas), and use the molar mass of oxygen (O2, approximately 32.00 g/mol) to find the mass. The calculation shows that the mass of oxygen is approximately 11.7 g.
