2,2 moles of plutonium: 13,248711938.1023 atoms.
48,177 134 32.1023 atoms
There is 25.0 moles Oxygen
it is 20456678
If the chlorine is in its normal state of diatomic molecules, there are 16.0 moles of chlorine atoms in 8.00 moles of chlorine. The number of atoms is then 16 times Avogadro's number = 9.64 X 1024, to the justified number of significant digits.

The answer is 2,1077494515.10e+23 atoms.
44 moles of atoms
2,89 moles of aluminium contain 17,40398707673.1023 atoms.
4,80 moles of Fe contain 28,9062761136.10e23 atoms.
Number of moles = mass / molar mass, so the answer is the one with the greatest molar mass. This is plutonium.
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
0.125 moles x 6.02x10^23 atoms/mole = 7.53x10^22 atoms
4.2 moles of CS2 contain 8,4 moles sulfur.
Avogadro's number times 5.6 (or about 33.6 times ten to the 23rd power.
48,177 134 32.1023 atoms
0.0845 moles of tungsten is equal to 0,50887.10e23.
There is 25.0 moles Oxygen
