I have the five isotopes of zinc, each with its percent by mass abundance and the compostition of its nucleus. Now I need to calculate the approximate Atomic Mass of zinc as I would find it in nature and listed on the Periodic Table. How do I go about doing this? in the first isotope there are 30p and 34n and the percent mass abundance is 48.89% the second isotope is 30p and 36n and 27.81% third isotope is 30p and 37n 4.11% fourth isotope is 30p and 38n and 18.57% and the fifth isotope has 30p and 40n and 0.62%.
Any help anyone can provide I would greatly appreciate!
THANKS

Best Answer - Chosen by VotersFor each isotope calculate the mass number (# protons + # neutrons) for each atom. This is its approximate atomic mas. Then calculate the average mass for all the isotopes. Covert the percentages to decimals then multiply each mass number by the decimal of the abundance and add all the terms(64 x 0.4889) + (mass # 2 + 0.2781) + (......) + (......) + ( .....)
The atomic mass of zinc (Zn) is approximately 65.38 u (atomic mass units).
The atomic mass of zinc is approximately 65.38 atomic mass units.
grams. This means that one mole of zinc weighs the same as the atomic mass of zinc in grams, which is approximately 65.38 grams.
The density of pure copper is: 8.94 g/cm^3 The density of pure zinc is: 7.13 g/cm^3
The relative atomic mass of zinc chloride (ZnCl2) is calculated by adding the atomic masses of its constituent elements (zinc and chlorine). The atomic mass of zinc is approximately 65.38 g/mol, and each chlorine atom has an atomic mass of about 35.45 g/mol. Therefore, the relative atomic mass of zinc chloride is around 136.28 g/mol.

The atomic number of an element is the number of protons in its nucleus. Zinc has an atomic number of 30, so all isotopes of zinc will have 30 protons. Therefore, the atomic number of zinc-67 is also 30.

To find the molar mass of ZnF2 (zinc fluoride), you would calculate the sum of the atomic masses of zinc (Zn) and two fluorine atoms (F). The atomic mass of zinc is 65.38 g/mol, and the atomic mass of fluorine is 18.998 g/mol. Therefore, the molar mass of ZnF2 is 65.38 + 2(18.998) = 103.376 g/mol.
Zink is a non metal element. Atomic Mass of it is 65.39.
Relative atomic mass: Zinc= 65 Nitrogen= 14 Oxygen= 16 Nitrate= nitrogen and oxygen= 30 Formula for zinc nitrate: Zn(NO3)2 NO= 30 NO3= 90 Zn= 65 Zn(NO3) x2 = Zn(NO3)2= 310 Formula mass (molecular mass)(Mr) of zinc nitrate = 310
65.39amu
Zink is a meta element. Atomic mass of it is 65. Atomic number of it is 30.
The relative atomic mass of zinc chloride (ZnCl2) is calculated by adding the atomic masses of its constituent elements (zinc and chlorine). The atomic mass of zinc is approximately 65.38 g/mol, and each chlorine atom has an atomic mass of about 35.45 g/mol. Therefore, the relative atomic mass of zinc chloride is around 136.28 g/mol.
.06x molar mass of zinc which is the atomic mass so 3.9228 g
