Question

8. At a given temperature a particular volume of air can hold a maximum of 25 grams of water vapor, and the amount of water vapor present in that volume of air is 20 grams calculate the relative humidity of air:-
80%
100%
20%
25%​

Answer 1

the humidity is :

80.percent

Answer 2

Answer:

given = 25Gm of water vapor and 20 grams volume

to find =  relative humidity of air.

solution ;-

apply the formula of relative humidity that is ,

relative humidity =  m / M X 100%

here m is mass of water vapour

so,

      25 / 20 X 100 =  80%

so the option 1st 80 % IS correct answer. so the relative humidity of air is 80%
