If water vapor with the 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?

Respuesta :

Took a test and the answer was that the water vapor had remained the same. (35.0 grams)

Answer:

35 grams

Explanation:

Mass does not change with the state of matter.

If you always keep the same mass you will always keep the same number of moles n, and the same number of molecules of watter.

It may have different volume and pressure, but as long as there is not any loss of matter the mass will remain the same.
