(2.16x10^24 atoms) x ( 1 mole/ 6.022x10^23 atoms) = 0.3586848223x10^1 which your answer should be 3.59 moles
2,80 1024 atoms of silicon equals 0,465 moles.
The answer is 15,2 moles.
1,67.1024 argon atoms is equal to 2,773 moles.
56 moles × (6.02 × 1023) = 3.37 × 1024 atoms
To find the number of moles in 2.16 x 10^24 atoms of lead, you would divide the number of atoms by Avogadro's number, which is 6.022 x 10^23 atoms/mol. Thus, 2.16 x 10^24 atoms of lead is equal to 3.59 moles.
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.
