.06x molar mass of zinc which is the atomic mass so 3.9228 g
65.38(4) g mol-1
This is the mass number.
Atomic mass from my Periodic Table for Zinc is 65.38. This means 1 mole of naturally occurring zinc has a mass of 65.38 grams. If your zinc sample is pure zinc then: (mass of your sample)/(65.38 grams) = # moles of zinc.
the atomic mass of zinc is 65.390000
65.39amu
Zink is a meta element. Atomic mass of it is 65. Atomic number of it is 30.
.06x molar mass of zinc which is the atomic mass so 3.9228 g

Zink is a non metal element. Atomic Mass of it is 65.39.
The formula of zinc fluoride is ZnF2. Therefore, its molar mass is the sum of the atomic mass of zinc and twice the atomic mass of fluorine: 65.39 + 2(18.999) = 103.39; the last digit is depressed because it may not be significant, since the atomic mass of zinc (at least in my reference) has only four significant digits.
Properties of Zinc : Atomic number; 30 Atomic Mass; 65.37g.mol Melting Point; 420 C Boiling Point 907 C
This is the mass number.

30 electrons. Zinc-66 stands for Zinc having 66 as the Atomic Mass. We know Zinc has 30 protons and we can assume that it's in a stable state so there would be 30 electrons. This means there's 36 neutrons. (30[protons] + 36[neutrons] = 66[atomic mass]
Atomic mass from my Periodic Table for Zinc is 65.38. This means 1 mole of naturally occurring zinc has a mass of 65.38 grams. If your zinc sample is pure zinc then: (mass of your sample)/(65.38 grams) = # moles of zinc.
The atomic weight of zinc is: 65,38 The atomic weight of fluorine is: 18,998 403 2 The molecular mass of zinc difluoride is by consequence: 65,38 + 2 x 18,998 403 2. And M= 103,406 g/mol (for the anhydrous molecule)
