In order to figure out this answer, you will first need to know the mixing ratio of air that has a temperature of 35°C and a relative humidity of 77%. (Remember relative humidity is the actual mixing ration divided by the mixing ratio at which the are would be saturated with water.) Once you know the actual mixing ratio, then you need to know the saturation mixing ratio at 25°C. The difference between these two mixing ratios will be the amount of water that will condense out of a liter of the air in the room when it is cooled to 25°C. You will then need to multiply this amount of water by the total volume of the room and that will give you the total amount of water that condenses.
