Mole Concept Visualizer
Watch mass become moles, then particle clouds, while Master Alchem turns Avogadro's number into a scale story.
Mass -> moles -> particles
Convert a measurable mass into moles and representative particles.
Moles
0.9992
mass divided by molar mass
Particles
6.017 x 10^23
moles multiplied by Avogadro's number
Scale checkpoint
The dots are symbolic: even a tiny mole-scale sample contains particle counts so large they must be handled with scientific notation.
moles = mass / molar mass
Use when grams are known.
mass = moles x molar mass
Use when preparing a measured sample.
particles = moles x 6.022 x 10^23
Use for atoms, molecules, ions, or formula units.

Master Alchem's scale trick
A mole is a counting bridge. First move from grams to moles, then from moles to the particle world.
