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.
