Mass determination is a scientific research area focused on measuring the mass of an object or substance. This can include weighing objects using scales, utilizing mass spectrometry techniques to analyze the composition of molecules, or studying the gravitational pull of an object to determine its mass. Mass determination is important in various fields such as chemistry, biology, and physics, as it provides crucial information about the properties and characteristics of a given material. This research area is essential for understanding the behavior and interactions of different substances in various scientific disciplines.
