Final answer:
A gravimetric analysis is a quantitative chemical analysis method that involves separating an analyte from a sample and calculating its concentration based on mass measurements and stoichiometry.
Step-by-step explanation:
A gravimetric analysis is a quantitative chemical analysis method that involves the separation of an analyte from a sample by a physical or chemical process, determining its mass, and then calculating its concentration based on stoichiometry.
In this method, the sample is subjected to a treatment that causes a change in the physical state of the analyte, allowing its separation from other components of the sample.
By measuring the mass of the analyte or a known component of the analysis system, along with the known stoichiometry of the compounds involved, the concentration of the analyte can be calculated.
