Quizplus · Accepted Answer

The normal percent of water vapor in dry air is typically in the range of 0-4%. While the amount of water vapor in the air can vary depending on factors such as temperature and location, the average relative humidity in the atmosphere is around 70%, and this corresponds to a water vapor content of about 0.25% by volume. However, this value can be lower in arid regions and higher in humid areas, but overall, the range of 0-4% is considered normal for dry air.
