Calculate he number of moles you have by taking the Mass / molar mass. if you have 1000 grams ; then 1,000 g / 151.001 g/mol = X g moles. Then multiply by Avogadros # = 6.022140857 × 10^23 molecules per g mole. The result is the # of molecules of MnSO4.The number of molecules in one mole is the same for all substances; this number is known as Avogadro’s number (6.022140857 × 1023).How to Convert Molecules to Moles. Converting between molecules and moles is done by either multiplying by or dividing by Avogadro’s number: To go from moles to molecules, multiply the number of moles by 6.02 x 1023. To go from molecules to moles, divide the numbers of molecules by 6.02 x 1023.
- The number of particles in a substance can be calculated using:
- Number of particles = Avogadro constant × the amount of substance in mol.
- Calculate the number of water molecules in 0.5 mol of water.
- Number of water molecules = Avogadro constant x amount of substance in mol.
