So I'm given that the barometer reads 738.5 torr, and :delta: = 2.35 cm, SO, I know what an open-end barometer's pressure is Pgas = Patm - :delta: h when Pgas < Patm
What is the pressure in atms?
738.5 - 2.35 cm = 736.15 torrs x (1 atm /760 torr) which gives me .9686 atm
But the book says .9408 atm!
What am I doing (trivially) wrong?!
