<u>Answer:</u> The partial pressure of oxygen gas is 57.8 kPa
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the partial pressure of oxygen gas, we use the law given by Dalton, which is:
We are given:
Total pressure of the tank, = 201.4 kPa
Vapor pressure of helium, = 125.4 kPa
Vapor pressure of carbon dioxide, = 18.2 kPa
Putting values in above equation, we get:
Hence, the partial pressure of oxygen gas is 57.8 kPa
Answer:
<h3>Step 1: </h3>
To relate the volume and molarity of a solution at two different concentrations, the expression used is :
M₁V₁ = M₂V₂
<h3>
step 2:</h3>
(2M) V₁ = (0.15M)(250ML)
V₁ = 18.75
step 3:
