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.
Do you divide equivalent fractions?
Any fraction divided by an equivalent fraction will always equal one.Any fraction divided by an equivalent fraction will always equal one.Any fraction divided by an equivalent fraction will always equal one.Any fraction divided by an equivalent fraction will always equal one.
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.
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.
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 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.
How does 3.45 liters equal in moles?
liter = unit of volume mole = unit of concentration
What formula do you use to find a solution stregth?
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.
One mole of N2 gas at STP will occupy what volume?
22.4 L. At STP 1 mole of any gas will always be equal to 22.4 L.
What is the mole fraction of solute in a 3.82 m aqueous solution?
To find the mole fraction of solute, you need to know the moles of solute and solvent. In this case, the moles of solute can be calculated by multiplying the molarity of the solution by the volume of the solution. Once you have the moles of solute and solvent, you can find the mole fraction of solute by dividing the moles of solute by the total moles of solute and solvent.
