How do you get from 100g of magnesium to find the number of atoms
Expert Answer
For a chemical compound or a molecule, the number of moles can be defined as the ratio of the mass to that of molecular mass. The mathematical relation is shown below:

Mass Number of moles Molar mass
The number of atoms which are present in one mole of a given substance is equal to the Avogadro’s number=6.022×1023.
The number of atoms present in a given number of moles of a given substance can be calculated using the following relation:

Number of atoms=Number of moles xN Number of molesx6.022 x 1023
The mass of Magnesium is given to be 100 g.
The atomic mass of Magnesium is 24.305g/...
