WebWe know that the atomic number of zinc is 30 and the atomic average mass number is about 65. Neutron = 65 – 30 = 35. Therefore, a zinc atom has thirty-five neutrons. Based … Web26 de nov. de 2024 · Atomic mass of Zinc is 65.409 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams.

Solved I . Question 10 of 16 Submit What is the mass number
WebThese values give for zinc the same isotopic moment as mercury 1-41 and a mean mass number of 65-452. Subtracting 0-065 for the packing fraction and 0-007 for change to the chemical scale we get Atomic weight of zinc = 65-380 di 0-02. A value in exact agreement with the best chemical determinations.
