what is the gram atomic mass of zinc? is gram atomic mass the same as atomic mass ?
The gram atomic mass of an element is the atomic mass of the element with the word grams following. The gram atomic mass of oxygen is about 16 grams.
so for zinc it would be 65.3 ?
The gram atomic mass of an element is the mass of one mole of that element expressed in grams. It is also sometimes referred to as molar mass. This value is obtained by summing the atomic masses of all the atoms present in a single molecule or formula unit of the substance.
To find the gram atomic mass of zinc, we need to know the atomic mass of zinc. The atomic mass of an element is the weighted average mass of all the naturally occurring isotopes of that element. It can be found on the periodic table.
The atomic mass of zinc (Zn) is approximately 65.38 atomic mass units (amu). Therefore, the gram atomic mass of zinc is also 65.38 grams per mole (g/mol).
Now, to answer your second question, yes, the gram atomic mass is essentially the same as the atomic mass. The only difference is the unit of measurement. Atomic mass is generally expressed in atomic mass units (amu), while gram atomic mass is expressed in grams per mole (g/mol).
So, to summarize, the gram atomic mass of zinc is 65.38 g/mol, and it is equivalent to its atomic mass of 65.38 amu.
Two technical points, but no, it would be 65.39 grams.
1. 65.39 is the atomic mass of Zn on my periodic table; if you want it to the tenths place it would be rounded to 65.4.
2. Technical point #2 is you didn't write the word grams after you wrote 65.3. I think my profs would count that incorrect. It may seem insignificant to the student but you wrote the atomic mass of Zn, not the gram atomic mass.
