Air in the alveoli has a partial pressure of nitrogen of 569 mm Hg, oxygen is 104 mm Hg, water is 40 mm Hg, Carbon dioxide is 47 mm Hg. What is the total pressure? What is the percent composition of each gas (partial pressure/total pressure x 10)

I really don't know but I'm sure a teacher can help you.

To find the total pressure in the alveoli, we need to sum up the partial pressures of all the gases present. In this case, we have nitrogen, oxygen, water vapor, and carbon dioxide.

The total pressure is calculated by adding the partial pressures of each gas:
Total pressure = nitrogen partial pressure + oxygen partial pressure + water partial pressure + carbon dioxide partial pressure

Total pressure = 569 mmHg + 104 mmHg + 40 mmHg + 47 mmHg
Total pressure = 760 mmHg

Therefore, the total pressure in the alveoli is 760 mmHg.

To find the percent composition of each gas, we can use the formula:
Percent composition = (partial pressure/total pressure) x 100

For each gas:

Nitrogen:
Percent composition of nitrogen = (569 mmHg / 760 mmHg) x 100
Percent composition of nitrogen = 74.87%

Oxygen:
Percent composition of oxygen = (104 mmHg / 760 mmHg) x 100
Percent composition of oxygen = 13.68%

Water vapor:
Percent composition of water vapor = (40 mmHg / 760 mmHg) x 100
Percent composition of water vapor = 5.26%

Carbon dioxide:
Percent composition of carbon dioxide = (47 mmHg / 760 mmHg) x 100
Percent composition of carbon dioxide = 6.18%

Therefore, the percent composition of each gas in the alveoli is approximately:
- Nitrogen: 74.87%
- Oxygen: 13.68%
- Water vapor: 5.26%
- Carbon dioxide: 6.18%

To find the total pressure in the alveoli, you need to sum up the partial pressures of all the gases present. In this case, you have the partial pressures of nitrogen (569 mm Hg), oxygen (104 mm Hg), water vapor (40 mm Hg), and carbon dioxide (47 mm Hg).

Total pressure = Partial pressure of nitrogen + Partial pressure of oxygen + Partial pressure of water vapor + Partial pressure of carbon dioxide

Total pressure = 569 mm Hg + 104 mm Hg + 40 mm Hg + 47 mm Hg

Total pressure = 760 mm Hg

The total pressure in the alveoli is 760 mm Hg.

To find the percent composition of each gas, you can use the following formula:

Percent composition = (Partial pressure / Total pressure) x 100

Let's calculate the percent composition for each gas:

For nitrogen:
Percent composition of nitrogen = (569 mm Hg / 760 mm Hg) x 100 = 74.87%

For oxygen:
Percent composition of oxygen = (104 mm Hg / 760 mm Hg) x 100 = 13.68%

For water vapor:
Percent composition of water vapor = (40 mm Hg / 760 mm Hg) x 100 = 5.26%

For carbon dioxide:
Percent composition of carbon dioxide = (47 mm Hg / 760 mm Hg) x 100 = 6.18%

Therefore, the percent composition of each gas in the alveoli is approximately:
- Nitrogen: 74.87%
- Oxygen: 13.68%
- Water vapor: 5.26%
- Carbon dioxide: 6.18%
