Vanadium does not have moles but rather formula units. The formula unit for vanadium is a single atom. Therefore, the number of formula units in any number of atoms is equal to the number of atoms divided by Avogadro's Number, in this instance 7.17 X 10-3 formula units.
One mole of anything is 6.022 X 10^23 (Avogadro's number )
Vanadium has 23 electrons and protons; the number of neutrons is specific for each isotope.
Number of neutrons in a vanadium isotope = Mass number - 23
How many moles are there in 9.0333x1024 atoms of helium
1,67.1024 argon atoms is equal to 2,773 moles.
4.66715966 × 1024
The answer is 15,2 moles.
If it is 1.54 moles of Br atoms then the answer is 9.274 X 1023 atoms.If it is 1.54 moles of Br2 molecules then the answer is 1.855 X 1024 atoms.
2,80 1024 atoms of silicon equals 0,465 moles.
How many moles are there in 9.0333x1024 atoms of helium
1,67.1024 argon atoms is equal to 2,773 moles.
4.66715966 × 1024
The answer is 15,2 moles.
56 moles × (6.02 × 1023) = 3.37 × 1024 atoms
2.26*1024
2.26*1024
If it is 1.54 moles of Br atoms then the answer is 9.274 X 1023 atoms.If it is 1.54 moles of Br2 molecules then the answer is 1.855 X 1024 atoms.
1.20x10^24 atoms x 1 mole/6.02x10^23 atoms = 1.99 moles
(2.16x10^24 atoms) x ( 1 mole/ 6.022x10^23 atoms) = 0.3586848223x10^1 which your answer should be 3.59 moles
If you meant 8.9 * 10^24, then there are 14.78 moles. 8.9 e24 (# of atoms) / 6.02 e23 (# of atoms in a mole) = 14.78 (# of moles)
