The lowest concentration of oxygen that ...

The lowest concentration of oxygen that can support aquatic life is about `1.3xx10^(-4)mol//L` . The partial pressure of oxygen is `0.21 atm` at sea level.
What is the lowest partial pressure of oxygen that can support life ?
`k_(H)(O_(2))=11.3xx10^(-3)mol//L.atm`

A

`0.02 atm`

B

`0.10 atm`

C

`1.0 atm`

D

`10 atm`

Text Solution

Verified by Experts

The correct Answer is:
2

The minimum partial pressure is
`P=(S)/(K_(H))=(1.3xx10^(-4)mol//L)/(1.3xx10^(-3)mol//(L atm))=0.10atm`.
