Question

Oxygen gas of 27.4 L at 25℃ with the pressure of 1.30 atm and 8.50 L of helium gas at 25℃ with a pressure 2.00 atm was pumped into a tank with a volume of 5.81 L at 25℃. Calculate the partial pressure of oxygen in the 5.81L tank.

A) 1.30 atm

B) 4 atm

C) 6.13 atm

D) 3.30 atm

Answer 1

To calculate the partial pressure of oxygen in the tank, use Dalton's Law of Partial Pressure.

Step-by-step explanation:

To calculate the partial pressure of oxygen in the tank, we need to use Dalton's Law of Partial Pressure. According to Dalton's Law, the total pressure in the tank is the sum of the partial pressures of each gas.

First, let's calculate the partial pressure of oxygen:
Partial Pressure of Oxygen = (Volume of Oxygen Gas / Total Volume of Tank) * Total Pressure of Tank
Partial Pressure of Oxygen = (27.4 L / 5.81 L) * (1.30 atm + 2.00 atm)
Partial Pressure of Oxygen = 3.24 atm

Therefore, the partial pressure of oxygen in the 5.81L tank is 3.24 atm.
