I hope this will help a bit (Forgive me of its wrong pls)
Answer:
Vapor pressure of water = 23.14torr
Explanation:
When you made a solution, vapor pressure decreases following Raoult's law:
<em>Where P is vapor pressure and X mole fraction</em>
As vapor pressure of water is 23.77torr we must find the mole fraction of water knowing the solution is 1.500m glucose (That is 1.500 moles of glucose per kg of water = 1000g of water).
1000g of H₂O are, in moles (Molar mass: 18.02g/mol):
1000g H₂O ₓ (1mole / 18.02g) = 55.5 moles of H₂O.
As we know now the solution contains 55.5 moles of water and 1.5 moles of glucose. Thus, mole fraction of water (Solvent) is:
Replacing in Raoult's law, pressure of water above the solution is:
<h3>Vapor pressure of water = 23.14torr</h3>
Gas Giants are usually bigger than Terrestrial Planets. Gas Giants also have thicker atmospheres, and have gaseous surfaces. Terrestrial planet tend to be smaller, and have solid surfaces. In our solar system, Mercury, Venus, Earth (home), and Mars are Terrestrial planets. While Jupiter, Saturn, Uranus (the planet), and Neptune are Gas Giants. Gas Giants are also known as Jovian planets.
Hello there!
Alexander Fleming was actually known for discoveries and of what he has invented. He made many things such as medicine, and also, certain substances such as enzyme lysozyme. He made many awards, noble prize, and other highly certificates that made him a very interesting person. This was the kind of person Alexander Fleming was.
I hope this helps you!
Answer:
So, H2O means two atoms of hydrogen mixed with one atom of oxygen. All pure water is the same, two parts hydrogen to one part oxygen. ... Water cannot be separated by any physical means.
