Find the limiting reactant, theoretical product amount, leftover reactant, and percent yield from a balanced two-reactant equation with clear steps…

Plan a stock-solution dilution with stock volume, final volume, target concentration, and diluent volume.

Calculate solute moles and mass for a target molarity and final volume, correcting the mass for stated purity.

Round a coefficient to three significant figures, express it with a power-of-ten exponent, and keep the rounding step explicit.

Scale a reagent from a base amount and equivalents, then convert the required amount to grams with molar mass.

Convert base amount and loading basis into reagent moles, mass, and liquid volume using equivalents, mol%, or ppm.

Analyze a first-order reaction with the integrated rate law, remaining concentration, fractional conversion, and half-life.

Calculate a component partial pressure from total pressure and mole fraction using Dalton’s law.

Calculate ideal osmotic pressure from molarity, temperature, and van’t Hoff factor using π = iMRT.

Plan a three-step synthesis by multiplying step yields, estimate final amount, and identify the lowest-yield bottleneck.
