Total atoms
9.0332 × 10²³ atoms
Formula units (molecules) present
3.0111 × 10²³
Atoms per formula unit
3
Moles of atoms
1.5 mol
Set atoms per formula unit to 1 for a monatomic element such as helium or a metal.
What this calculator does
Converts moles into formula units and then into the total number of atoms when each unit contains more than one atom.
What your result means
The headline is the total atom count; the stats separate formula units from atoms.
Formula and working
N = n × N_A ; total atoms = N × atoms per unit
- 1
Collect the inputs
Amount of substance (n) = 0.5 mol; Atoms in each formula unit = 3
- 2
Apply the formula
N = n × N_A ; total atoms = N × atoms per unit
- 3
Result
Total atoms = 9.0332 × 10²³ atoms
