Answer

Answer:

C. 96.82 kPa

Explanation:

Step1: Recall Dalton's law

According to Dalton's law of partial - pressures, the total pressure ($P_{total}$) of a gas mixture is the sum of the partial pressures of its components. So, $P_{total}=P_{air}+P_{water\ vapor}$.

Step2: Rearrange the formula

We want to find $P_{air}$, so we can rewrite the formula as $P_{air}=P_{total}-P_{water\ vapor}$.

Step3: Substitute the given values

Given $P_{total} = 100.18$ kPa and $P_{water\ vapor}=3.36$ kPa. Then $P_{air}=100.18 - 3.36=96.82$ kPa.
