Q. The octanol/water partition coefficient of paracetamol as log Po/w is 0.49.
Paracetamol has a water solubility of 1.4g/100 ml at 20°C. When extracted a
100ml water solution with 50ml of octanol, what mass of paracetamol is
extracted at 20°C?

Where am I going wrong? I don't need to hand this in or anything, just revising. Haven't done this in a while and so I'm confused...

Any help will be appreciated, I think I'm missing something obvious as is always the case when I get annoyed, lol.
