The partial pressures add to give the total pressure.
2.6 = x + 1.2 + 0.1
Solve for x, the oxygen partial pressure.
2.6 = x + 1.2 + 0.1
Solve for x, the oxygen partial pressure.
Partial pressure of oxygen = Total pressure - Partial pressure of carbon dioxide - Partial pressure of helium
Given:
Total pressure = 2.6 atm
Partial pressure of carbon dioxide = 1.2 atm
Partial pressure of helium = 0.10 atm
Partial pressure of oxygen = 2.6 atm - 1.2 atm - 0.10 atm
Partial pressure of oxygen = 1.3 atm
1. Start by listing the given partial pressures:
- Carbon dioxide (CO2): 1.2 atm
- Helium (He): 0.10 atm
2. Add up the partial pressures of carbon dioxide and helium:
1.2 atm + 0.10 atm = 1.3 atm
3. Subtract the sum of the partial pressures from the total pressure to find the partial pressure of oxygen:
2.6 atm - 1.3 atm = 1.3 atm
Therefore, the partial pressure of oxygen in the sealed vessel is 1.3 atm.
