Question

what is it called when the mass of atoms found in nature is determined by measuring the masses of the elements combined in chemical compounds, a large number of atoms must be used to make the measurement.

Answer 1

This process is called mass spectrometry. In mass spectrometry, a sample is ionized, typically by bombarding it with high-energy electrons, and the resulting ions are separated based on their mass-to-charge ratio. The mass of the ions can be measured using a mass spectrometer, and this allows the determination of the atomic masses of the elements present in the sample. To obtain accurate results, it is generally necessary to measure the masses of a large number of atoms, as the precision of the measurement increases with the number of atoms that are measured
