Answer:
The partial pressure of oyxgen O2 is 606 mmHg
Explanation:
Step 1: Data given
Percentage N2 = 22.8 %
The total pressure = 785.0 mmHg
Step 2: Calculate partial pressures
Partial pressure = percentage * total pressure
Partial pressure N2 = 0.228 * 785.0 mmHg
Partial pressure N2 = 179 mmHg
Step 3: Calculate partial pressure O2
Partial pressure O2 = 785.0 mmHg - 179.0 mmHg
Partial pressure O2 = 606 mmHg
OR (1 - 0.228) * 785.0 = 606 mmHg
The partial pressure of oyxgen O2 is 606 mmHg
