The relative humidity of air is $80%$ at $27^{o} C .$ .If the aqueous tension at the same temperature is $27 mm$ of $Hg .$ The partial pressure of water vapour in the air will be (in $mm$ of $Hg$ ).

Answer:

21.60

Solution:

Relative humidity $= \frac{P a r t i a l p r e s s u r e}{V a p o u r p r e s s u r e} \times 100$

$\Rightarrow \frac{P a r t i a l p r e s s u r e}{27} \times 100 = 80$

$\Rightarrow P a r t i a l p r e s s u r e = \frac{80 \times 27}{100}$

$∴ P a r t i a l p r e s s u r e = 21.6 m m$ of Hg
