if the total pressure of a container filled with oxygen gas, nitrogen gas and water vapor is equal to the pressure of what ?
A.oxygen only
B. oxygen and nitrogen only
C. water vapor only
D. All 3 gasses added together
Dalton's Law of Partial Pressures: The sum of the partial pressures of gases adds to total pressure.
To determine the pressure of the container filled with multiple gases, we can use Dalton's Law of Partial Pressures. According to this law, the total pressure is the sum of the partial pressures of each gas.
In this case, the container contains oxygen gas, nitrogen gas, and water vapor. So, the total pressure of the container is equal to the sum of the partial pressures of oxygen gas, nitrogen gas, and water vapor.
Therefore, the correct answer is option D. The total pressure of the container is the sum of the pressures of all three gases added together.
To calculate the partial pressures of each gas, you would need to know the mole fractions or the amount (in moles or mass) of each gas present. Once you have these values, you can calculate the partial pressures using the ideal gas law or the appropriate gas law equation.
The partial pressure of a gas is given by the equation:
Partial Pressure = Total Pressure * Mole Fraction
If you know the moles or mass of each gas, you can calculate the mole fraction by dividing the moles or mass of a specific gas by the total moles or mass of all the gases present.
By applying Dalton's Law of Partial Pressures and using the appropriate equations, you can determine the partial pressures of each gas and then add them together to find the total pressure of the container.
