What will be the partial pressure of He and O2 respectively, if 200ml of He at 0.66atm and 400ml of O2 at 0.52atm pressure are mixed in 400ml vessel at 20 C (temperature). Pls pls Pls help me........

partial pressure is the pressure of a individual gas when it is placed in a required vessel or in final vessel.
Hence the in the given problem He is initially 200 ml at 0.66atm but finally it is placed in a vessel of volume 400 ml .
#then P1×V1= P2×V2
p1=pressure of He in 200 ml vessel
v1= volume of He initially
p2=final partial pressure of He
v2=final volume of vessel
》》0.66×200=P2×400
》》P2=0.33 atms(partial pressure of He)
next initially O2 is present at 0.52 atm 400 ml and then it is placed in 400 ml vessel hence the partial pressure of O2 is 0.52 atm
》》partial pressure of He=0.33 atm
》》partial pressure of O2=0.52 atm
