How much Lt Oxygen in water

(1/4) > >>

Fish200398:
the solubility of oxygen in 1 lt water 25 c 1 atm is 28 ml. How much Lt O2 can be dissolve in 1 lt water 25 c 4 atm?

I though using PV=nRT which gives me PV=P2V2, V2 = 7ml.
I dont understand Henry Law...

Borek:
You can't use some randomly selected law to solve a problem that is described by another one. It won't ever work. But you are right mentioning Henry's Law, that's the one that should be used here.

Can you write the Henry's law? What does it say?

Fish200398:
Theres so many equations https://en.m.wikipedia.org/wiki/Henry%27s_law

Borek:
Sadly, wikipedia article is poorly written, no wonder you feel lost.

See if this formulation won't be better.

Fish200398:
C = k.P
C = Molarity
k = Henrys Law
P = Pressure

So, how i should find C?
