The concentration of water vapor in a sample of air that has a partial pressure of water of 0.91 torr and a total pressure of air of 735 torr is ppm. the concentration of water vapor in a sample of air that has a partial pressure of water of 0.91 torr and a total pressure of air of 735 torr is ppm. 0.81 0.12 8.1 ⋅ 10−4 1.2 1.2 ⋅ 103

Answer : The concentration of water vapor in a sample of air is,

Explanation : Given,

Partial pressure of water = 0.91 torr

The total pressure of air = 735 torr

Parts per million (ppm) : It is defined as the mass of a solute present in one million parts by the mass of the solution.

Now we have to calculate the concentration of water vapor in a sample of air.

Now put all the given values in this formula, we get  concentration of water vapor in a sample of air.

Therefore, the concentration of water vapor in a sample of air is,

the answer is na (sodium)
