Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

This equation is educational: verify chemical identity, balanced stoichiometry, purity, activity, temperature, significant figures, apparatus, and laboratory safety independently.

Use internally consistent units and retain extra precision when carrying the result into another calculation.
