Question

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.
