Mole to molecule calc

• What is the formula for mole to Mole?

  The number of moles you have of a compound can be calculated by dividing the number of grams of the compound by the molecular mass of the compound. The formula looks like this: moles = grams of compound/molar mass of compound. 2. Plug your numbers into the formula.

• How do you calculate mole?

  You calculate the number of moles by dividing the mass of substance by the substance’s atomic or molecular weight. You then find the mole fraction by dividing the moles of one substance in a mixture by the total number of moles of all substances in the mixture.

• How do you calculate molecules from moles?

  Divide the known mass of the compound by its molar mass to calculate the number of moles. For example, suppose the mass of your sample of Na2SO4 is 20 g. The number of moles equals 20 grams /142 grams/mole = 0.141 moles.

• How do you calculate the mass of a mole?

  If you have a pure liquid or a solid, you use its density to calculate its mass and then divide the mass by the molar mass. If you have a solution, you multiply the molarity by the volume in litres. There are two steps: Multiply the volume by the density to get the mass. Divide the mass by the molar mass to get the number of moles.

  One molecule of cyclohexanol should produce one molecule of cyclohexene. One mole (mol) of cyclohexanol should produce one mole of cyclohexene. If 2.05 g of cyclohexanol is used (use the actual amount used in your experiment) convert this to moles by dividing by the molecular weight of cyclohexanol (MW = 100.2 g/mol).
