A 2.5L flask @ 15 degrees C cntains three gases. The partial pressure of N2 is 0.32 atm, and the partial pressure of the other two gases, He and Ne are 0.15 atm and 0.42atm respectivly. What is the total pressure in atm on the 2.5L flask?

To find the total pressure in the flask, we need to sum up the partial pressures of all the gases.

Given:
Partial pressure of N2 (P(N2)) = 0.32 atm
Partial pressure of He (P(He)) = 0.15 atm
Partial pressure of Ne (P(Ne)) = 0.42 atm

To find the total pressure (P(total)):
P(total) = P(N2) + P(He) + P(Ne)

P(total) = 0.32 atm + 0.15 atm + 0.42 atm

P(total) = 0.89 atm

Therefore, the total pressure in the 2.5L flask is 0.89 atm.

To find the total pressure in the 2.5L flask, you need to sum up the partial pressures of the three gases.

Given:
Partial pressure of N2 = 0.32 atm
Partial pressure of He = 0.15 atm
Partial pressure of Ne = 0.42 atm

To find the total pressure, you simply add up the partial pressures:

Total pressure = Partial pressure of N2 + Partial pressure of He + Partial pressure of Ne

Total pressure = 0.32 atm + 0.15 atm + 0.42 atm

Total pressure = 0.89 atm

Therefore, the total pressure in the 2.5L flask is 0.89 atm.

Remember Dalton's Law that

Ptotal = Pgas1 + Pgas2 + Pgas3 + .....
