converts the quantity in the specified instance cheminst to targetunit.
converts to SI base units.
- cheminst must be a ChemicalInstance or EntityInstance expression.
- The targetunit can be a canonical unit, a Quantity expression, a QuantityVariable expression or a "PhysicalQuantity" Entity.
- When targetunit is a Quantity, the result will have the same unit as targetunit.
- When targetunit is a QuantityVariable expression or a "PhysicalQuantity" Entity, the result will use the corresponding canonical unit.
- A targetunit specification can also be one of the following unit systems: "SIBase", "SI", "Imperial", "Conventional" or "Metric".
- ChemicalConvert uses standard temperature, 293.15 K (20 °C), and standard pressure, 101325 Pa (1 atm), as the default values for "Temperature" and "Pressure".

Generalizations & Extensions (2)
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 ofto :
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:
