Assuming that you are trying to find the number of moles in an elemental sample, you would take the mass of the sample, and divide by the atomic weight of the substance. This will give you the number of atoms. You this divide this by Avogadro's number (6.0221415 x 1023). This will give you the number of moles in the sample.
I even saw a mole once, but it was chased under the porch by a cation. ■
A mole is a unit of measurement used in chemistry to express amounts of a substance. One mole is equal to the number of atoms in 12 grams of carbon-12, which is approximately 6.022 x 10^23. To calculate the number of moles in a sample of a substance, you divide the mass of the sample by the molar mass of the substance (mass per mole).
depends on what you are trying to convert to moles if you start with atoms, molecules or formula units, then you use the ration "1 mol / 6.02 x 10^23" if you start with a compound, such as H2O, then you would use the formula "1 mol/ 18 g" the 18 grams is the mass off of the Periodic Table if you start with a gas, then the formula is "1 mol/ 22.4 L"

How do you calculate number of mole in 36grams of oxygen?
1 mole O = 15.9994g 36g O x 1mol O/15.9994g O = 2.3 moles O
How do you calculate mass of an unknown liquid in grams per mole?
To calculate the mass of an unknown liquid in grams per mole, you would need to know the substance's molar mass (g/mol) and the amount of the substance in grams. Then, divide the mass in grams by the molar mass to get the value in grams per mole.
How do you calculate number of molecules in a mole?

How do you calculate energy per mole of photons if you know joules per photon?
To calculate the energy per mole of photons from the energy per photon, you need to multiply the energy per photon by Avogadro's number (6.022 x 10^23) to account for the number of photons in a mole. The formula is: Energy per mole of photons = Energy per photon x Avogadro's number.

How do you calculate a mole of an atoms weight in grams?
To calculate the weight of a mole of an atom in grams (molar mass), you add up the atomic masses of all the atoms in one mole of the substance. This can be found on the periodic table and is usually given in atomic mass units (amu). The molar mass is expressed in grams per mole.

What is the mole fraction of HCl in an aqueous solution that is 27.2 percent HCl by weight?
To find the mole fraction of HCl in the solution, we first need to calculate the molar mass of HCl (H=1g/mol, Cl=35.5g/mol). Then, determine the number of moles of HCl in 100g of the solution. Finally, calculate the mole fraction of HCl by dividing the moles of HCl by the total moles of solute and solvent in the solution.
How do you calculate energy per mole of photons if you know joules per photon?
To calculate the energy per mole of photons from the energy per photon, you need to multiply the energy per photon by Avogadro's number (6.022 x 10^23) to account for the number of photons in a mole. The formula is: Energy per mole of photons = Energy per photon x Avogadro's number.
