If water vapor with mass of 35.0 grams is cooled and condensed into water in a closed system such as a closed glass jar, what is the mass of the water after the water vapor completely condenses
The mass of the water vapor and the mass of the liquid water will be the same.
If the mass of the water vapor is 35.0 grams, the mass of the water after it completely condenses will also be 35.0 grams.
To determine the mass of the water after the water vapor completely condenses, we need to know the molecular weight of water (H2O) and the conditions under which the condensation occurs.
The molecular weight of water (H2O) is calculated as follows:
2(1.0079 g/mol) + 15.999 g/mol = 18.015 g/mol
Since the closed system doesn't allow for the escape of any substances, the total mass remains constant. So, the mass of the water after the water vapor completely condenses will be the same as the initial mass of the water vapor, which is given as 35.0 grams.
To find the mass of the water after the water vapor completely condenses, you need to understand the process of condensation and the conservation of mass.
Condensation is the process where a substance changes from a gaseous state to a liquid state. In this case, water vapor is being cooled and condensed into water.
During condensation, there is no loss or gain of mass. The total mass of the water in the closed system remains constant. So, the mass of the water vapor before condensation is equal to the mass of the water after condensation.
Therefore, the mass of the water after the water vapor completely condenses in the closed glass jar would also be 35.0 grams.
