2.61 X 10^24 atoms of gold (1 mole Au/6.022 X 10^23)
= 4.33 moles of gold
4.2 X 10^24 atoms of gold / 6.022 X 10^23 atoms per mol) = 7.0 moles of gold
The formula unit of gold is generally considered to be a single atom. Therefore, the answer is 5.6 X Avogadro's Number or about 3.4 X 1024.
2.26*1024
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
4.2 X 10^24 atoms of gold / 6.022 X 10^23 atoms per mol) = 7.0 moles of gold
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
The formula unit of gold is generally considered to be a single atom. Therefore, the answer is 5.6 X Avogadro's Number or about 3.4 X 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
