∙ 9y agobecause mole fraction doesnot depend on volume
There can be no answer. A quart can be expressed as a fraction only in the context of another quantity of volume.
The molar volume, symbol Vm,[1] is the volume occupied by one mole of a substance (chemical element or chemical compound) at a given temperature and pressure. It is equal to the molar mass (M) divided by the mass density (ρ). It has the SI unit cubic metres per mole (m3/mol),[1] although it is more practical to use the units cubic decimetres per mole (dm3/mol) for gases and cubic centimetres per mole (cm3/mol) for liquids and solids.
Avogadro's number is the number of molecules in a mole of a substance. This is expressed as 6.022 141 29 E23 /mol. This is defined as the number of atoms in 12 grams of carbon12. A mole of any gas has this number of molecules. Any fraction of that mole must be divided into the number.
It is equal to 1.
For Ideal gases, mole fraction=volume fraction
because mole fraction doesnot depend on volume

the mole fraction of oxygen= 37/100 0.37 the mole fraction of Nitrogen= .63 that equals to give 1
liter = unit of volume mole = unit of concentration

Yes - as long as the pressure and temperature are constant.
Your question doesn't have a single answer. In Chemistry solution strength is usually calculated in moles pe liter of mole per kilogram or as a mole fraction ( moles per mole) but can also be mass per liter, mass per mass, volume per volume, percent by mass, or percent by volume.
22.4 L. At STP 1 mole of any gas will always be equal to 22.4 L.
1 mole of a gas at S.T.P always has the volume 22.414dm3 so number of moles multiply by 22.414 (molar volume) is equal to total volume at S.T.P , volume at other conditions may be calculated by equation of states, P1V1/T1 = P2V2/T2
The mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume and the density of water is 1.00g per mL that of ethanol is 0.789 grams per mL and 70/18. A mole fraction in chemistry is the amount that is divided by the total amount of all constituents.
The mole fraction of Oxygen = 21/100= .21
