Applications  (1)

How many moles of tricalcium diphosphate,

, can be produced from 5 grams of calcium hydroxide when it reacts with excess phosphoric acid to produce
and water? Start by balancing the chemical reaction:

Compute the stoichiometric ratio of


Convert 5 g of

to moles and multiply by the stoichiometric ratio to find the moles of

Possible Issues  (3)

If the molar mass of a chemical entity cannot be determined, ChemicalConvert remains unevaluated:

If properties of a chemical at a nonstandard temperature and pressure are unavailable, ChemicalConvert remains unevaluated:

Multiple physical quantity keys can lead to unexpected results. Here, the "Mass" key has higher precedence than "Volume", so it is used for the conversion and the results replace the initial volume:
