Lesson-specific diagram for Aqueous stoichiometry and precipitation. It visualizes the reasoning sequence tied to $cV\to n\xrightarrow{\nu_B/\nu_A}n\to m\text{ or }c$. Text alternative: Aqueous stoichiometry begins with molarity-volume conversion, then uses a balanced molecular/net ionic reaction and limiting-reactant logic. Choose a representation that matches the chemical scale and evidence; do not infer more precision or mechanism than the data support.
