To calculate humidity, you can use the formula:
\[
\text{Humidity} = \left( \frac{\text{Actual Density}}{\text{Saturation Density}} \right) \times 100\%
\]
Given:
- Actual density of water vapor = 9 g/cm³
- Saturation density of water vapor = 18 g/cm³
Now, substituting the values into the formula:
\[
\text{Humidity} = \left( \frac{9\, \text{g/cm}^3}{18\, \text{g/cm}^3} \right) \times 100\% = \left( \frac{1}{2} \right) \times 100\% = 50\%
\]
Therefore, the humidity is **50%**.
The correct answer is **B. 50%**.
\[

Therefore, the humidity is **50%**.
The correct answer is **B. 50%**.
