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.

When zinc reacts wiht sulfuirc acid what mass of hydrogen is produced from 31.8g of zinc?
Zn + H2SO4 -> ZnSO4 + H2 I assume zinc limits? 31. 8 grams Zn (1 mole Zn/65.41 grams)(1 mole H2/1 mole Zn)(2.016 grams/1 mole H2) = 0.980 grams hydrogen gas
What is the formula for zinc nitride?
The chemical formula for zinc nitrate is Zn(No3)2
What chemical element is represented by Zn?
Zn represents ZINC, having atomic number 30 and mass number 65.39.
What is the number of atoms in 1.88 moles of Zn?
To find the number of atoms in 1.88 moles of Zn, you would multiply the number of moles by Avogadro's number, which is 6.022 x 10^23 atoms/mol. Therefore, there are approximately 1.13 x 10^24 atoms in 1.88 moles of 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
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
An atom has 29 electrons and protons and 35 neutrons what is the mass number?
30 The atomic number is the number of protons
How many neutrons are there in a zinc Zn atom with a mass number of 66?
A zinc atom with a mass number of 66 has 34 neutrons. This is determined by subtracting the atomic number (number of protons) from the mass number, since the mass number represents the sum of protons and neutrons.
What is the mass in grams of 0.040 moles Zn?
0,040 moles Zn equal 2,614 g.
What is the mass number of an element that has thirty protons thirty-five neutrons and thirty electrons?
mass = p + nSo mass number is 30+35= 65. This is an u nstable (not natural) Zn-65 isotope (halftime 250 d.)

How many atoms are in 7.1 mol Zn?
From my understanding as there is only one mole of zinc which means the mass is 65.4 . Then to get the number of particles the answer is simply 1(the number of moles) x 6.02 x 10 ^ 23. is this correct this is not the answer just a further question ...
How many zinc atoms are present in 20.0 g Zn?
Molar mass of Zinc = 65.4 g mol-1 No. of moles of 20.0 g of Zinc = 20.0 / 65.4 = 0.305810397 mol No. of atoms = 0.305810397 L (where L is the Avogadro constant) = 1.8416 x 1023
