Answer to Question #150062 in General Chemistry for Mackenzie

Question

A gas is created through downward displacement at 280C in a lab. The atmospheric pressure (the total pressure) during the lab is 104.5 kPa . Using the formula Ptotal= Pgas + Pwater vapour, what is the pressure exerted by the gas ?

Answer 1

$$P_{water} = P_{total}-P{gas}$$

$$P_{water} = 104.5-102.3 = 2.2 kPa$$
