If the partial pressures of CO₂ and H₂O in exhaled air are each 30.0 torrs at 37.0°C, the mass (g) of CO₂ is 16 grams and of H₂O is 6.7 grams exhaled in 1 h of sleep.
In a mixture of gases, every constituent gasoline has a partial pressure which is the notional stress of that constituent fuel as if it on its own occupied the whole volume of the authentic aggregate at the same temperature.
Partial pressure is the force exerted by using gas. The sum of the partial pressures of all of the gases in an aggregate equals the total pressure. Partial stress is extremely crucial in predicting the movement of gases. don't forget that gases generally tend to equalize their stress in areas that are connected.
in keeping with Dalton's law of partial pressures, the whole pressure through a combination of gases is the same as the sum of the partial pressures of every of the constituent gases. The partial strain is defined as the pressure each gasoline might exert if it on its own occupied the quantity of the combination at an equal temperature.
Using PV=nRT
n=(PV)/(RT)
= ((23/760) x 300L)/(0.0821x (273+26))
= 0.369846
Mass of CO2 = 0.369846 x molar mass of CO2= 16 grams
Mass of H2O = 0.369846 x molar mass of H2O= 6.7 grams
