Final answer:
To find the new volume of oxygen gas at 45.0 °C and 594.05 mmHg from STP conditions, one can use the combined gas law. The initial volume, temperature, and pressure (V1, T1, P1) are used along with the final temperature and pressure (T2, P2) to calculate the final volume (V2). Temperature should be in Kelvin, and pressure should be in the same units.
Step-by-step explanation:
The volume of a sample of oxygen gas at different conditions can be determined using the combined gas law, which combines Charles's Law, Boyle's Law, and Gay-Lussac's Law.
In this case, we are looking to find the new volume of oxygen gas when the temperature is increased to 45.0 °C and the pressure is changed to 594.05 mmHg from standard temperature and pressure (STP) conditions.
To find the new volume, we use the following formula: V1/T1 * P1 = V2/T2 * P2, where V1 is the initial volume, T1 is the initial temperature, P1 is the initial pressure, V2 is the final volume, T2 is the final temperature, and P2 is the final pressure. Remember to convert temperatures to Kelvin and pressures to the same units if necessary before doing the calculation.
If the oxygen gas behaves ideally, the volume it occupies at different conditions can be determined with this formula.
