Concept explainers
Interpretation:
The information about the relative number of ions and the mass percent of each element in the formula
Concept introduction:
Law of definite composition – The law of definite compositions was introduced by Joseph Proust. This law states that a particular compound is composed of the elements in the exact same proportions, irrespective of the source.
The formula to calculate the mass fraction of an element in a compound is,
The formula to determined the mass percent of an element in a compound is,

A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
