# partial pressure- chemistry

#1
how would i work out partial pressure with no mol value.
i rearranged to get pressure on its own so
p(cl2)= 3.5x10-4/ p(SbCl5) and them /divide by p(SbCl3) and got 9.3582 x10-3

This is a small task pm. I can share with you all the steps on how to calculate this. reach out to me through my whatsApp +254797004634
Do you mind explaining it instead?

The partial pressure is directly proportional to the moles.

It is the mole fraction x the total pressure.

The sum of the partial pressures = the total pressure.

Hi i forgot to post the link to the question and just did so, its given no mol so how would i do mole fraction x total p?

Like I said the partial pressure is directly proportional to the moles.

K = pp(SbCl3) * pp(Cl2)/pp(SbCl5)

just rearrange to get pp(Cl2)
