what is the total pressure in a gas mixture of 100 mm hg O2, 820 mm hg N2, and 1.5 mm hg CO2?
To find the total pressure in a gas mixture, you need to sum up the partial pressures of each individual gas component.
In this case, you have three different gas components: O2, N2, and CO2. Each gas component has a given pressure: 100 mmHg for O2, 820 mmHg for N2, and 1.5 mmHg for CO2.
To find the total pressure, you simply add up the three partial pressures:
Total Pressure = Partial Pressure of O2 + Partial Pressure of N2 + Partial Pressure of CO2
Total Pressure = 100 mmHg + 820 mmHg + 1.5 mmHg
Calculating this expression gives you the answer:
Total Pressure = 921.5 mmHg
