Why mole fraction does not dependend upon temperature?
because mole fraction doesnot depend on volume
What does a quart equal as a fraction?
There can be no answer. A quart can be expressed as a fraction only in the context of another quantity of volume.
What does the term molar volume mean?
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.
What is the most appropriate to express number of molecules per volume?
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.
When the numerator of a fraction is equal to its denominator the fraction is equal to?
It is equal to 1.
State relation between mole fraction and Volume fraction?
For Ideal gases, mole fraction=volume fraction
Why mole fraction does not dependend upon temperature?
because mole fraction doesnot depend on volume
What is the mole fraction of solute and solvent is equal to?
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.
Why mole fraction of gases is always equal to unity?
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.
Does the mole of solution is equal to mole of solute plus mole of solution?
No, the mole of solution is not equal to the mole of solute plus the mole of solvent. The mole of solution refers to the total amount of moles in a given volume of solution, which includes both the solute and the solvent.
What is the mole fraction of oxygen in a gas mixture that is 37 percent oxygen and 63 percent nitrogen in volume?
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.
Is mole percent of a gas is equal to its volume percent?
No, mole percent and volume percent are not necessarily equal for a gas. Mole percent is the ratio of the moles of a gas to the total moles of all gases in a mixture, while volume percent is the ratio of the volume of a gas to the total volume of all gases in a mixture. The two can be equal only if the gases have the same molar volume at the given conditions.
What is the relationship between mole fraction and concentration in a solution?
The mole fraction of a substance in a solution is the ratio of the number of moles of that substance to the total number of moles in the solution. Concentration, on the other hand, is the amount of a substance present in a given volume of the solution. The mole fraction and concentration are related because the mole fraction can be used to calculate the concentration of a substance in a solution.
How do you convert mole fraction to volume fraction of liquid?
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
What is the relationship between mole fraction and mass fraction in a given mixture?
The relationship between mole fraction and mass fraction in a mixture is that the mole fraction of a component is equal to its mass fraction divided by its molar mass, multiplied by the total mass of the mixture. This relationship helps in understanding the proportion of each component in the mixture based on their masses and molar masses.
What does a quart equal as a fraction?

How does 3.45 liters equal in moles?
liter = unit of volume mole = unit of concentration
