Problem

An aquatic species needs atleast

4 \text{ mg/litre}

\text{O}_2

for their survival. The solubility of

\text{O}_2

in water at

273 \text{ K}

and

1 \text{ atm}

pressure is

2.21 \times 10^{-3} \text{ mol litre}^{-1}

. The partial pressure of

\text{O}_2

above water (in atmosphere at

273 \text{ K}

) needed for survival of species is : (1)

0.56 \text{ atm}

(2)

5.525 \times 10^{-3} \text{ atm}

(3)

5.525 \text{ atm}

(4)

0.056 \text{ atm}
