How to make a stoichiometry table

Draw the reaction and choose View › Stoichiometry table. Pick the limiting reagent and its mass; the other amounts follow from their equivalents, with the theoretical yield below.

Steps

  1. Draw the reaction, for example ethanol and acetic acid to ethyl acetate.

  2. Choose Main menu › View › Stoichiometry table.

  3. Pick the Limiting reagent and type its Mass (mg).

  4. Set each other reactant's Equiv. Its mmol and mass follow.

  5. Type the Isolated product (mg) to compare with the Theoretical yield.

  6. Copy table copies it, and Place on page puts it beside the reaction.

Molecular weights come from the structures as drawn.

Reactions and arrowsHow to draw a reaction schemeDraw or insert the reactants, press W and drag a reaction arrow after them, write the conditions above it with the Text tool, then add the products after the arrow. Or press / and type the whole reaction as reaction SMILES.
