Answer :

The relative humidity for the first container is 100%.

The relative humidity for the second container is 66.67%.

The relative humidity for the third container is 50%.

The relative humidity for the fourth container is 75%.

What is relative humidity?

Relative humidity is a percentage that represents the amount of water vapor in the air at a given temperature compared to the maximum possible water vapor amount at that particular temperature.

The relative humidity for the first container is calculated as;

R.H = volume of water vapor / total volume x 100%

R.H = 6/6 x 100%

R.H = 100%

The relative humidity for the second container is calculated as;

R.H = 6/9 x 100%

R.H = 66.67 %

The relative humidity for the third container is calculated as;

R.H = 6/12 x 100%

R.H = 50%

The relative humidity for the fourth container is calculated as;

R.H = 9/12 x 100%

R.H = 75%
