1. Can anyone help with this question?

(1) What is the PO2 of inspired air (PIO2) of a climber on the top of mount Everest where the barometric pressure is 33.3 kPa? (2) What would it be at sea level where the atmospheric pressure is 101 kPa ? In both cases assume that water vapour pressure is 0.5 kPa. Give your answers in kPa.

The partial pressure of an inspired gas(in this case O2) = the fractional concentraion of the inspired gas x the local barometric pressure

I think you need to work out the percentage of oxygen in water, which shouldn't be too hard, and convert it into a fraction
