请翻译下面的英语化学题目What is the mass of one carbon atom in atomic mass unit(amu)What is the m
What is the atomic mass of carbon?Atomic Mass:Atomic mass is a number that represents the amount of matter in an atom or isotope of a certain element, specifically the number of protons and neutrons. Atomic mass is calculated as an average mass of the different isotopes of each element. ...
This unit is use to describe the actual mass of an atom or compound. It differs than molar mass because molar mass assumes Avogadro's number of atoms or molecules in the sample while amu is the mass of a single atom or molecule.Answer and Explanation: There is 12.011 amu o...
Question: What mass of carbon has the same number of atoms as 78.54 grams of chromium? Molar Mass The molar mass of an atom or a compound is the mass of one mole of that compound. The molar mass of the atom or compound can be used as a conversion factor to convert the m...
The atomic mass is the mass of an atom. Although the SI unit of mass is the kilogram, the atomic mass is often expressed in the non SI-unit dalton, where one dalton is defined 1/12 of the mass of a single carbon-12 atom, at rest. The protons an...
What is the center of an atom called?Atoms:Atoms are the smallest indivisible working unit of matter. It is composed of three subatomic particles: neutrons, electrons, and protons. Neutrons are neutrally charged whereas electrons are negatively charged. Protons are the subatomic particles of an ...

It is 1.992648 xx 10^(-23) g ~~ 1.99 xx 10^(-23)g It can be obtained by dividing gram atomic mass of carbon (12 g) with Avogadro's No. (N(A)) ((12g))/(6.022xx10^(23))~~1.99xx10^(-23)g.
The nucleus of each elemental atom contains protons, neutrons and electrons. Although each element normally has an equal number of protons and electrons, the number of neutrons can vary. When atoms of a single element like carbon have different numbers o
The mass of one C atom is: A6.023×1023g B1.99×10−23g C2.00g D12 gSubmit Assertion : One atomic mass unit is defined as one twelfth of the mass of one C-12 atom. Reason : C-12 is the least abundant isotope of carbon and has been choosen as the standard. AIf both asser...
