Final answer:
Calculating the final temperature and final pressure of the oxygen gas requires additional data. The volume can be calculated using the ideal gas law, and the mass by multiplying the number of moles with the molar mass of oxygen.
Step-by-step explanation:
The question posed involves calculating various properties of oxygen gas under certain conditions using the ideal gas law, which is 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.
Answering each part of the question:
- The final temperature cannot be calculated from the given information alone. Additional information, such as a change in volume or pressure, is needed.
- The final pressure is also unknown without additional data regarding changes in temperature or volume.
- To calculate the volume of the gas, use the ideal gas law. Rearrange the law to solve for V (V = nRT/P), and plug in the values, making sure to use the correct units and convert temperature from Celsius to Kelvin by adding 273.15.
- To find the mass of the oxygen gas, use the molar mass of oxygen (32 g/mol), and multiply it by the number of moles (3 moles in this case).
With these calculations, the student can find the volume and mass of the oxygen gas, but more details are required to calculate the final temperature and pressure.
