Answer:
Step-by-step explanation:
The partial pressure of the air in the sample can be found using the formula for Dalton's law of partial pressures, which states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual gases:
Total pressure = partial pressure of gas 1 + partial pressure of gas 2 + ...
In this case, we have two gases: air and water vapor. We know the total pressure of the mixture and the partial pressure of the water vapor, and we want to find the partial pressure of the air. We can set up the equation as follows:
Total pressure = partial pressure of air + partial pressure of water vapor
Substituting the given values:
100.18 kPa = partial pressure of air + 3.36 kPa
Solving for the partial pressure of air:
partial pressure of air = 100.18 kPa - 3.36 kPa
partial pressure of air = 96.82 kPa
Therefore, the partial pressure of the air in the sample is 96.82 kilopascals.
