Avogadro y el puente entre mundos: presentación visual

Section role: supports Section 3 by providing visual grounding for Amadeo Avogadro's constant and connecting the group simulation results from Section 2 to formal chemical quantities. Slides: (1) Title — 'El Puente entre Mundos: De lo Visible a lo Invisible'; (2) Amadeo Avogadro — bullets: historical context, hypothesis on gas volumes, legacy; (3) El Número de Avogadro — bullets: 6.022 x 10^23, visual scale analogies like grains of sand covering continents; (4) ¿Qué es un Mol? — bullets: definition as chemical dozen, bridge between macroscopic grams and microscopic particles; (5) Masa Molar — bullets: definition of g/mol, connection back to relative masses explored in Section 2; (6) Ejemplo paso a paso 1 — conversion from grams of Carbon to moles; (7) Ejemplo paso a paso 2 — conversion from moles of Water to number of molecules; (8) Conexión con la Práctica — prep for individual problem solving in Section 4. Closing slide: '¿Cómo nos ayuda el mol a pesar átomos sin verlos?' — hands control back to the teacher for wrap-up and guided practice.
