Assume that the water vapor is an ideal gas. So,
PV = nRT
For conversion, 760 mmHg = 101325 Pa and 1,000 L = 1 m³
(187.5 mmHg)(101325 Pa/760 mmHg)(5 L)(1 m³/1,000 L) = n(8.314 m³Pa/molK)(65+273 K)
Solving for n,
n = 0.0445 mole water
Since the molar mass of water is 18 g/mol,
Mass of water vaporized = 0.0445*18 = 0.8 g water vaporized
Hence,
Percentage of water vaporized = 0.8/1.2 * 100 =<em> 66.7%</em>
Answer:
The main difference between cyclohexane and benzene is that cyclohexane contains 12 hydrogen atoms bonded to six carbon atoms, two hydrogen atoms per each carbon atom whereas benzene contains six hydrogen atoms bonded to six carbon atoms, one hydrogen atom per each carbon atom.Jan 25, 2018

Answer: No one. All these molecules are nonpolar.
Explanation: Dipole-dipole attractions occur only between polar molecules. To know if a molecule is polar, you have to observe if their dipole moment (μ) is different from 0. You can do this by observing the vectors of charge in each molecule.
In all the molecules of the alternatives, the overall molecule is nonpolar (the sum of the vectors is equal to 0). So, these molecules are attracted only by induced dipole forces (weak forces that exist between nonpolar molecules).
For F2, this molecule is nonpolar because is composed of equal atoms. So, there isn't an atom which pulls the charge for itself.
hi cut person cute picture what's up my friend
