A gaseous mixture containing 2 g H2,8 g He,22 g O2 is enclosed in a vessel. The gas with highest partial pressure is?

The correct option is A HeGiven, H2−2g He−8g O2−22g The partial pressure of any gas is directly proportional to the number of moles. Moles = weightmass H2=2/2=1 He=8/4=2 O2=22/32=0.68 Helium has the highest moles so, it has the highest pressure. Hence, option A is the correct answer.
