Now I see that your 3 equations and my one equation are the same.

If you plug in values of first and second equations of yours into third one, what you get is my equation.

So your conclusion is...

for ideal gas,
density = (PM/RT). M is molecular weight.
P = (density*RT)/M
I guess the right hand side in above equation when multiplied by mass fraction of a species would give partial pressure...
