What is the relative humidity of a sample of air that holds 0.014 kg of moisture at 21°C, with a maximum capacity of 0.015 kg?

To determine the relative humidity of the air sample, it's essential to understand that relative humidity is defined as the ratio of the actual amount of moisture in the air to the maximum amount of moisture that the air can hold at a given temperature, usually expressed as a percentage.

In this case, the actual amount of moisture present in the air is 0.014 kg, and the maximum capacity of moisture that the air can hold at 21°C is 0.015 kg. The formula for calculating relative humidity is:

[

\text{Relative Humidity} = \left( \frac{\text{Actual Moisture}}{\text{Maximum Moisture}} \right) \times 100

]

Plugging in the values:

[

\text{Relative Humidity} = \left( \frac{0.014 \text{ kg}}{0.015 \text{ kg}} \right) \times 100

]

Calculating this gives:

[

\text{Relative Humidity} = \left( 0.9333 \right) \times 100 = 93.33%

]

Thus, when expressed as a percentage, this rounds to 93.3%. This value indicates that
