There are approximately 1.93 x 10^24 atoms in 3.20 moles of aluminum. This calculation is based on Avogadro's number, which states that 1 mole of any substance contains 6.022 x 10^23 particles (atoms, molecules, ions, etc.).
1,67.1024 argon atoms is equal to 2,773 moles.
The answer is 15,2 moles.
The number of moles is 0,528.
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 mole of atoms = 6.022 x 1023 atoms 6.2mol x 6.022 x 1023 atoms/mol = 3.7 x 1024 atoms Al
2,80 1024 atoms of silicon equals 0,465 moles.
1,67.1024 argon atoms is equal to 2,773 moles.
The answer is 15,2 moles.
56 moles × (6.02 × 1023) = 3.37 × 1024 atoms
3.7 moles sodium (6.022 X 10^23/1 mole Na) = 2.2 X 10^24 atoms of sodium
The gram molecular mass of Al2O3 is 2(26.982) + 3 (15.999) = 101.96. Therefore, the number of moles of Al2O3 is 291.257/101.96 = 2.857 moles. Each mole contains two moles of aluminum atoms; therefore the number of aluminum atoms in this mass equals 2 X 2.857 X 6.022 X 1023 = 3.4410 X 1024 atoms.
To convert atoms to moles, you divide the number of atoms by Avogadro's number, which is 6.022 x 10^23 atoms/mol. So, 1.53 x 10^24 atoms of carbon divided by Avogadro's number is equal to 2.54 moles of carbon.
2.26*1024
The number of moles is 0,528.
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.
