A gas mixture with a total pressure of 741 mmHg contains each of the following gases ....HELP?

A) Partial pressure He = 760 - (124 + 230 + 194) = 212 mm Hg B) PV = n RT (212/760 atm) (11.6 L) = n (0.0821 Latm/molK) (265 K) n = 0.149 mol He X 4.00 g/mol = 0.595 g He.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
