How to determine the relative humidity of the air?

In such problems, the temperature is usually indicated – we ignore it. We take the highest water vapor content in the air and take it as 100%. We take the content given as x%. Next, we make up the proportion
I will explain the solution with an example: let the maximum be 12.8 g
Air content 9 g
Then 12.8 – 100%
9 – x%
x = 9 × 100 / 12.8 ≈ 70
Relative humidity – 70%. According to this principle, everything is decided
