Question

Two bottles are connected with a valve. In bottle A, there are 2.4 L of nitrogen gas at 1.8 atm. In bottle B, there are 4.8 L of nitrogen gas at 1.8 atm.
After opening the valve, what is the pressure of nitrogen gas?

Answer 1

Answer:

1.8 atm

Explanation:

For bottle "A"

P1 = 1.8 atm V1 = 2.4L, P2 = ?, V2 = 2.4 + 4.8 L = 7.2 L,

Thus using P1•V1 = P2•V2, we have;

P2 = (1.8 × 2.4)/7.2 = 0.6 atm

For bottle "B"

P1 = 1.8 atm, V1 = 4.8L, P2 = ?, V2 = 7.2L,

P2 = (1.8 × 4.8)/7.2 = 1.2 atm

We will now add the individual pressures of each bottle;

Total pressure = P(A) + P(B)

Total pressure = 0.6 + 1.2

Total pressure = 1.8 atm.
