because mole fraction doesnot depend on volume
The volume fraction of a substance is equal to the mole fraction for ideal gas mixture
10 to the power of 7?
Dependent variable: growth of crystals Independent variable: temperature.

because mole fraction doesnot depend on volume
For Ideal gases, mole fraction=volume fraction
The volume fraction of a substance is equal to the mole fraction for ideal gas mixture
To find the mole fraction of oxygen, first convert the percentages to fractions: 37% oxygen is 0.37 and 63% nitrogen is 0.63. Since the total mole fraction in a mixture is 1, the mole fraction of oxygen would be 0.37/(0.37 + 0.63) = 0.37/1 = 0.37. Therefore, the mole fraction of oxygen in the gas mixture is 0.37.
To calculate the vapor pressure of the water solution with a mole fraction of HgCl2 of 0.163 at 25°C, you would need to use Raoult's Law. The vapor pressure of the solution would be equal to the mole fraction of water multiplied by the vapor pressure of pure water at that temperature. The vapor pressure of HgCl2 can be ignored since its mole fraction is given.
The mole fraction of oxygen gas in air is approximately 0.21. This means that out of every 1 mole of air, 0.21 moles are oxygen gas molecules.
When the mole fraction of solute and solvent is equal, it means that both components are present in equal amounts in the solution. This would correspond to a mole fraction of 0.5 for both the solute and solvent.
Mole fraction is dimensionless. It's the amount of moles of species "A" divided by the total amount of moles in the mixture. So "mole A / mole total" equals "dimensionless". To add clarity in the use of mole fractions, one could add as "unit" mole A / mole "mixture".
You need the balanced symbol equation for the reaction. The numbers in front of the formulae show the mole ratios. For example, in the thermal decomposition of calcium carbonate: CaCO3 --> CaO + CO2 The equation is balanced. The mole ratio between CaCO3 and CO2 is 1:1 because there is 1 mole of CaCO3 for every mole of CO2
It is 100%.
Like a pressure, but with non-ideality Use as a pressure Fugacity = mole fraction of gas * total pressure Mole fraction of CO2 in atmosphere? 383 ppmv
The mole fraction of gases is not always equal to unity. The mole fraction of a gas in a mixture is equal to the number of moles of that gas divided by the total number of moles of all gases in the mixture. It is a dimensionless quantity that ranges from 0 to 1.
