What this calculator does
Moves between mass, molar mass, amount of substance and particle count for one pure substance.
What your result means
The headline converts your mass into moles; the stats show the reverse conversion and the molar mass implied by mass divided by moles.
Formula and working
n = m ÷ M ; m = n × M ; N = n × N_A
- 1
Collect the inputs
Mass (m) = 58.44 g; Molar mass (M) = 58.44 g/mol; Or start from an amount (n) = 1 mol

Apply the formula
n = m ÷ M ; m = n × M ; N = n × N_A
- 3
Result
Moles from the mass you entered = 1 mol
