The mass number of Zn, that is Zinc is 30. It means that it's nucleus contains 30 protons in it. Atomic weight being 65.4. It means average mass number of neutrons is 35.4. This fraction comes because of 'average' number of neutrons present in different 'Isotopes' of Zinc. You will find it interesting to note that Chromium (24 mass number.),Manganese (25),Cobalt (27),Nickel (28), Copper (29) and your Zinc (30) are the important trace element sitting horizontally in Periodic Table around Very important element Iron(26) which is most useful for formation of Hemoglobin in Human body.

How many moles are in 22.5 grams of zinc?
For this you need the atomic mass of Zn. Then take the mass in grams and divide it by the atomic number (multiplied by one mole for units to cancel) to find number of moles. Zinc's atomic mass is 65.4 grams.22.5 g Zn / (65.4 grams) = .344 moles Zn
How many grams are in 671.89 moles of zinc?
For this you need the atomic mass of Zn. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.671.89 moles Zn × (65.4 grams)) = 10.3 grams Zn

0,040 moles Zn equal 2,614 g.
What is the most common isotope of uranium?
The most common isotope of zinc is the one with mass number 64; the atomic number of zinc is 30, which means each zinc nucleus contains 30 protons, and the mass number is defined as the sum of the numbers of neutrons and protons. Therefore, the number of neutrons is (64 - 30) or 34.
What is the formula mass for zinc nitrate?
