not correspond to the microscopic mass. the macroscopic mass implies a certain isotopic distribution while microscopic refers to the mass of the most common isotope of oxygen that is o-16. remember the macroscopic mass is also called molecular weight or atomic weight. how to find isotopic mass?
Molar masses of elements First, you require finding the molar mass of the given element. The molar mass in grams is equal to the atomic weight of the element represented in atomic mass units. You can find them on the periodic table. ...
Atomic Mass Unit An Atom, being very small in size and mass, is not easy or convenient to measure with a normal measuring unit. Previously, scientists used experiments to measure the mass of an atom in relation to another. A unit of mass used to describe the mass of the atomic and suba...
Do remember that the atomic number is the number of protons (or positive charges) in a nucleus. It was a discovery made by Henry G J Moseley. Moseley found that certain lines in the X-ray spectrum moved each time he was using a new element. He rearranged the different e...
Atomic Mass Atoms are so small, it is difficult to discuss how much they weigh in grams. Use atomic mass units. an atomic mass unit (amu) is o
