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%
