10. If the partial pressure of nitrogen is 600 mmHg and the total atmospheric pressure is 760 mmHg, what is the partial pressure of oxygen? Desmos scientific calculator 760 mmHg 140 mmHg 160 mmHg 300 mmHg

## Step 1<br />The problem involves the concept of partial pressure in the context of atmospheric pressure. The total atmospheric pressure is the sum of the partial pressures of all the gases present in the atmosphere. In this case, the total atmospheric pressure is 760 mmHg, and the partial pressure of nitrogen is 600 mmHg.<br /><br />## Step 2<br />To find the partial pressure of oxygen, we subtract the partial pressure of nitrogen from the total atmospheric pressure. This is because the total pressure is the sum of the partial pressures of all gases.<br /><br />### **The formula used here is:**<br />### \( \text{Partial pressure of oxygen} = \text{Total atmospheric pressure} - \text{Partial pressure of nitrogen}## Step 3stitute the given values into the formula:<br /><br />### \( \text{Partial pressure of oxygen} = 760 \, \text{mmHg} - 600 \, \text{mmHg} \)
