Assume a gas is contained in the flask. A manometer,the h(a) has a formula of P(gas)=P(atm)-h and h(b) of the other manometer has a formula of
P(gas)=P(atm)+h.
By the way h stands for height
Calculate the pressure in the flask in torr, atmosphere, and pascals if h(a) = 134 mm.
Calculate the pressure in the flask in torr, atmosphere, and pascals if h(b) = 210. mm.
Calculate the pressures in the flask in parts a and b (in torr) if the atmospheric pressure were instead 675 torr.
