a scuba driver is using eanx32, an enhanced nitrox gas mixture. this mixture contains 32% oxygen with 68% nitrogen. if the cylinder is at a pressure of 250 kpa, what is the partial pressure of oxygen?
XO2 = 0.68
pO2 = XO2 x Ptotal
Yep. DrBob222 is correct. Work out the rest of the steps using your calculator or perhaps brain.
To find the partial pressure of oxygen in the eanx32 gas mixture, we need to use the given information that the mixture contains 32% oxygen and 68% nitrogen.
First, we need to convert the percentage values to decimal form:
- Oxygen: 32% = 0.32 (in decimal form)
- Nitrogen: 68% = 0.68 (in decimal form)
Next, we can calculate the partial pressure of oxygen using the following formula:
Partial Pressure of Oxygen = Total Pressure * Fraction of Oxygen
Given that the cylinder is at a pressure of 250 kPa and the fraction of oxygen is 0.32, we can substitute the values into the formula:
Partial Pressure of Oxygen = 250 kPa * 0.32
Calculating this, we get:
Partial Pressure of Oxygen = 80 kPa
Therefore, the partial pressure of oxygen in the eanx32 gas mixture is 80 kPa.
