How do you find number of atoms?
- Use the periodic table to determine the molar mass of the element.
- Divide the given mass in grams by the molar mass to find the number of moles.
- Multiply the number of moles by Avogadro's number to obtain the number of atoms.

There are 92.1486 grams of Nickel in 1.57 moles.
How many atoms are in 2.5 moles?
There are 45.165 X 1023 atoms in 2.5 moles of SO2. We reach this conclusion by using Avogadro's number, which is the number of fundamental units in a mole and equals 6.022 X 1023.
How much atoms are in a mole?
6.022 × 1023 atoms The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
How do you calculate number of atoms?
# of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro's number and its equal to 6.022*1023 atoms/mole. It can also be molecules per mole. In the above formula density times volume is just the mass.
