Homework Answers
before adding Ar gas total pressure of gas is 2 atm and partial pressure of two gas is
PHe = 1 atm
PNe = 1 atm
After adding of Ar total pressure is 4 atm, thus partial pressure of Ar is 2 atm, now partial pressure of all three gas is
PHe = 1 atm
PNe = 1 atm
PAr = 2 atm
According to above data we can conclude that option first and fourth is right and option second and third is wrong.
Folloeing statement are incorrect
partial pressure of He has doubled
all three gases have equal partial pressure
