You have three containers each of which is connected to a fourth empty container. Three of the containers contain pure gases. In the first container oxygen is at 2 atm, nitrogen at 4 atm is in the second container, and argon at 1 atm is in the third. When you open the valve and mix the gases in the forth container, what is the pressure, PT, in the forth container

Answer: The total pressure is 7 atm

Step-by-step explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.


p_(total)=p_A+p_B+p_C...

Given :
p_(total) =total pressure of gases = ?


p_(O_2) = partial pressure of oxygen = 2 atm


p_(N_2) = partial pressure of nitrogen = 4 atm


p_(Ar) = partial pressure of argon = 1 atm

putting in the values we get:


p_(total)=2atm+4atm+1atm


p_(total)=7atm

Thus the total pressure is 7 atm
