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?
1
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 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
Is mole percent of a gas is equal to its volume percent?
Yes - as long as the pressure and temperature are constant.
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 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.
How can a mole be used to make conversions to the volume of gas?
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
What are the mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume-The density of water is 1.00g per mL and that of ethanol is 0.789 grams per mL?
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.
Does the mole of solution is equal to mole of solute plus mole of solution?
No. The mole of solution is equal to mole of solute plus mole of solvent (solVENT !, not solution)
