Why this conversion matters in chemistry
Catalytic turnover-number math sits on top of this conversion. A 1 mmol Pd catalyst charge is 6.022 × 10²⁰ Pd atoms; if the reaction makes 100 mmol of product, the TON is 100 product molecules per Pd atom. The constant of 6.022 × 10²⁰ particles per mmol comes directly from Avogadro's number scaled by the milli prefix (Nₐ × 10⁻³). In practice you reach for it when a mmol-scale prep ends up reported in the per-atom or per-molecule count that catalyst-loading and turnover calculations expect.
