Use this chemistry calculator to reproduce a named relationship with explicit quantities and units for study, laboratory planning, or an independent numerical check.

Analyte molar mass (g/mol)

Required number input.

Precipitate molar mass (g/mol)

Required number input.

Stoichiometric ratio (mol analyte/mol precipitate)

Optional number input.

Compute the gravimetric factor converting precipitate mass to analyte mass via molar mass ratio and stoichiometry. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Gravimetric factor

The resulting gravimetric factor returned as a number.

• Stoichiometric results assume the balanced reaction, stated purity, and complete conversion to the selected products. Yield, selectivity, side reactions, moisture, and measurement uncertainty must be handled separately.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check units and significant figures, compare the result with limiting cases, and use measured or source-specific constants where available. Laboratory, safety, and regulatory decisions require validated methods and appropriate uncertainty analysis.

• Analyte Mass From Precipitate

  Compute analyte mass from precipitate mass by applying the gravimetric factor.

• Percent Analyte Gravimetry

  Compute the mass percent of analyte in a sample from precipitate mass and gravimetric factor.

• Precipitate Mass From Analyte

  Compute the precipitate mass needed for a given analyte mass using the gravimetric factor.
