The water vapor content in the air ranges from almost nil when temperatures are well into the double digits below zero (C or F) and dew points are even lower. In contrast, saturated air at 104F results in 7% of the air. I doubt its ever really been THAT high tho.
it is 2 percent of the total volume of atmosphere, therefore 2/100*51,006,560,000,000 cubic metres (m^3) =1.0201312 x10 ^12m^3
Percent by Volume of Solute in Solvent = Volume Solute/ (Volume Solvent + Volume Solute) * 100% = 48/ 192 = 25%
According to the USGS and NOAA, a 1km³ cumulus cloud would weigh about 2.21 billion pounds, or about 1,105 tons (US). The same volume of dry air weighs about 2.22 billion pounds, which is why clouds float. Because it is less dense than air, in truth, it doesn't "weigh" anything. It has volume. If you sucked all the water vapor out of the air and put it in a bucket, though, using the below chart as a guide and the fact that water is 1kg per liter, and one liter of water is 0.1 cubic meters, you'd have 12,900,000,000 liters of water, which is 12.9 trillion kg. (It's enough to cover the earth's 510,072,000 km² surface with about 25mm of water. Because the earth's average rain fall is about 1 meter, you can figure that all of this water vapor is recycled every nine or ten days.) So, to convert that metric to US tons and answer your question, all of that means that there is approximately more than 14.2 billion US tons of water vapor in the atmosphere.

At 86 degrees Fahrenheit, or 30 degrees Celsius, the percentage of the atmosphere comprised of water is about 4. 24 percent. Less than 1 percent of that water is NOT on the layer of the atmosphere closest to the earth.
If the concentration of alcohol and water solution is 25 percent alcohol by volume, the volume of alcohol in a 200 solution is 50.
Water.
It varies. There is no single percentage value
3 to 4 percent
Yes, Saturn has an atmosphere. It is made of 75 percent hydrogen and 25 percent helium and has trace amounts of methane and water ice.
water vapor
The troposphere contains 75 percent of atmosphere's mass- on an average day the weight of the molecules in the air is14.7 lb..(sq. in.)- and most of the atmosphere's water vapor.
212.5 cm3
No one gas comprises 99% of the atmosphere, but nitrogen (~78.09%) and oxygen (~20.95%) together comprise about 99% of the atmosphere (on a dry basis, i.e. not including water vapor which can range from near 0% to 5%).
