Given-H2-x2212-2g -He-x2212-8g -O2-x2212-22g -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-xA0-xA0-

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?HeH2CO2O2

Given, 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.
