A tightly closed container contains air as well as water, Ask an Expert

Academics

A tightly closed container contains air as well as water vapor at STP. The mass of air in the container is 4.21 kg as well as the mass of water vapor in the container is 20.1 g.

(1) Compute as accurately as possible the mol fractions in PPM of the water vapor as well as of the air in the container.

(2) Compute the relative humidity of the air in the container.

(3) Presume we lower the temperature while keeping the pressure in the container constant. Approximate the temperature at which the water vapor in this container would begin to condense.
