Carbon is taken as a standard element because there is no other element whose nucleus has a balanced number of protons and neutrons in it. How to Calculate Atomic Mass? The combined masses of protons and neutrons account for nearly all the mass of an atom, the atomic mass of a single ...
I know how to calculate the amount of atoms if I am given the amount of grams of the element at hand. Here is an example: How many atoms are in 22 grams of sulfur? But in the question that I have been presented, the only information I have is the following:...
Knowing the relative fraction of each isotope of a particular element that occurs in nature allows you to calculate the atomic mass of that element, which, because it is an average, is not the mass of any one atom but a number that is between the heaviest and lightest isotopes pres...
Figure 4.15 In the periodic table, each element is represented by its chemical name, atomic number, chemical symbol, and average atomic mass.在元素周期表中每一个元素用它的化学名称,原子序数,元素符号,以及平均相对原子质量表示。 Determine the number of protons and the number of electrons in an ato...
The mass of a surface would be 0 - unless the density function is a surface mass density. Is that the case? (surfaces have no volume) Did you use cylindrical-polar coordinates? I'd have worked out the surface element in those coordinates... Why not divide the surface into rings ...

Exact value depends on so many factors I am not sure it is possible to calculate without lot of other data (sublimation speed is a function of the vapor pressure, that in turns depends on the air flow around the element; exact modeling of such things is typically a nightmare). No...
