as we define mole to be mass of the solute divided by molecular mass of the solute so all the solutes are taken in the solid form not in the liquid like we take 1L in molarity,so solids are generally independent of temp thats why both molality and mole fraction are independent of temperature

Why mole fraction does not dependend upon temperature?
because mole fraction doesnot depend on volume
When can volume fraction be equal to mole fraction?
The volume fraction of a substance is equal to the mole fraction for ideal gas mixture
Can you give me an example of a mole fraction?
10 to the power of 7?
How would you write a dependent and independent variable for growth of crystals in a faster rate depending on temperature?
Dependent variable: growth of crystals Independent variable: temperature.
What is the independent variable on Does the elasticity of rubber change with temperature?
temperature(it is whats changed on purpose)
Why mole fraction does not dependend upon temperature?
because mole fraction doesnot depend on volume
State relation between mole fraction and Volume fraction?
For Ideal gases, mole fraction=volume fraction
When can volume fraction be equal to mole fraction?
The volume fraction of a substance is equal to the mole fraction for ideal gas mixture
What is the mole fraction of oxygen gas in air?
The mole fraction of Oxygen = 21/100= .21
What is the mole fraction of HCl in an aqueous solution that is 27.2 percent HCl by weight?
The mole fraction of HCl is 0.34.
A phase diagram identifies the state of matter of a substance for specific combinations of?
Phase diagrams usually show phase transition boundaries relative to two variables. WHICH two variables depends on what they're trying to show, but usually is is two of the following: Temperature Pressure Volume/density Mole fraction Mass fraction ========== PT PV less commonly - TV Isobaric T vs mole fraction (e.g. melting point diagram) Isothermal P vs mole fraction (e.g. a vapor pressure diagram)
What is the mole fraction of oxygen in a gas mixture that is 37 percent oxygen and 63 percent nitrogen in volume?
the mole fraction of oxygen= 37/100 0.37 the mole fraction of Nitrogen= .63 that equals to give 1
What is the unit of mole fraction?
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".
Calculate the mole fraction of HCl in 20 percent aqueous solution?
The mole fraction of HCl in 20 percent aqueous solution is 0.21.
What is the mole fraction of each component if 3.9g of benzene is dissolved in 4.6g of toluene?
The molar mass of benzene (C6H6) is 78.11 grams per mole. The molar mass of toluene is 92.14 grams per mole. Mole fraction of a solute equals moles of solute divided by the moles of solute plus the moles of solvent. .5 of each is the mole fraction.
Why the relative lowering of vapour pressure is independent of temperature?
Relative lowering of vapour pressure is function of pressure of pure liquid and pressure of solutions when you increase temperature both the values increase and compensate the increase value, According to the Raoult's law, Psolvent = Xsolvent Po where Psolvent is the vapour pressure of the liquid solution, Xsolvent is its mole fraction in the solution and Po is the pure vapour pressure.
