How do you know 0.0 to 0.4 is the percent of volume of water vapor?

One method would be to weigh a desiccant and then expose it to your known target volume to allow it to dry the material. Then re-weigh the desiccant.
If your'e looking at a low % of water vapour, you should attempt to minimise the 'tare weight' of your desiccant. Crumbled calcium sulphate is a safe desiccant - just dry it out well beforehand.

What is the volume of 1 cu ft of water vapor at 1750 degrees F and atomspheric pressure when cooled to 100 degrees F?
Should this question be? = What is the volume of 1 cu ft of water vapor at 100 degrees F and atmospheric pressure? = It's initial volume doesn't matter as you only want to know what its final volume is.
How does snow changes to form water vapor?
Snow can melt and turn into water and evaporate, and then the water turns into water vapor.
What is water vapor in science?
Water vapor is water that has risen up from oceans rivers and from plants and trees in the form of steam.By the way does anyone know how a mothership is formed?
How do you know that clouds aren't just composed of water vapor?
Actually, clouds aren't even water vapor! Water vapor is invisible, and clouds aren't invisible. Clouds are in the liquid form of water, believe it or not. There may be water in solid form if ice is present in the cloud, but otherwise, clouds are fully liquid water.
Stream discharge is also know as what?
Steam is also water vapor.
Define Volume percent and write the equation?
i dont know hahaha
Can water only exist as a liquid?
no, it can be ice and snow and it can be evaporated
Given that the density of water is 1000 kg m3 what mass of water does the tank contain?
You would also have to know the volume of the tank.You would also have to know the volume of the tank.You would also have to know the volume of the tank.You would also have to know the volume of the tank.
Why does water form on the glass?
The Surface of the glass is cold. When hotter water vapor touches it, it condenses to form water(Vapor = 100 degree C) You Dont Know This?? I mean I'm 13!
5 N H2SO4 What is percent?
If you are asking what percent of H2SO4 that you have, I would need to know that volume of the 5M H2SO4
How do you know that water evaporates?
The volume of liquid water decrease.
How does water changes to water vapor during evaporation and where it goes after it evaporates?
i don't know i am trying to do my homework
