3.20 moles aluminum (6.022 X 1023/1 mole Al) = 1.93 X 1024 atoms of aluminum -------------------------------------------
How many moles are there in 9.0333x1024 atoms of helium
1,67.1024 argon atoms is equal to 2,773 moles.
The answer is 15,2 moles.
4.66715966 × 1024
3.20 moles aluminum (6.022 X 1023/1 mole Al) = 1.93 X 1024 atoms of aluminum -------------------------------------------
Convert 1.35 × 1024 atoms of carbon to moles of carbon
1 mole of atoms = 6.022 x 1023 atoms 6.2mol x 6.022 x 1023 atoms/mol = 3.7 x 1024 atoms Al
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.
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.
3.7 moles sodium (6.022 X 10^23/1 mole Na) = 2.2 X 10^24 atoms of sodium
4.66715966 × 1024
56 moles × (6.02 × 1023) = 3.37 × 1024 atoms
