5,82 x 1023 atoms of tungsten equal 0,966 moles.
This is equivalent to 1,4 moles.
9,003 x 1023 atoms of iron correspond to 1,495 moles.
A sample of 3,2x10 atoms of nickel is equal to 0,53.10e-23 moles.
1 mole has 6.023 x 1023 atoms So, in 3.05 moles there are 18.37 x 1023 atoms
To find the number of moles in 1.01e23 fluorine atoms, divide the given number of atoms by Avogadro's number, which is approximately 6.022e23. So, 1.01e23 F atoms / 6.022e23 atoms/mol ≈ 0.168 moles of F atoms.
The answer is B, 8.0 x 10^1 There are 6.023 x 10^23 atoms in one mole, of any substance. So simply divide 4.8 x 10^25 by 6.023 x 10^23, to get about 79.69 which if you convert into scientific notation, is about 8.0 x 10^1 the answer for me was A but that's on novanet
5.66 x 10^23 atoms of xenon is equal to 0.094 moles.
5.66 X 1023 atoms of xenon (1 mole Xe/6.022 X 1023) = 0.940 moles of xenon ------------------------------
This is equivalent to 1,4 moles.
9,003 x 1023 atoms of iron correspond to 1,495 moles.
A sample of 3,2x10 atoms of nickel is equal to 0,53.10e-23 moles.
6.02 X 1023 particles per mole X .75 moles = 4.52 X 1023 molecules.
0,25 moles F2
56 moles × (6.02 × 1023) = 3.37 × 1024 atoms
Atomic Mass of Na: 23.0 grams1.50 moles × (6.02 × 1023 atoms) = 9.03 × 1023atoms
The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / moleTo convert moles to atoms:atoms B = 2.47 mol B6.02 x 1023 atoms B = 1.49E+24 atoms B1 mol BMultiply by atoms per mole. Moles cancel out.
1 mole has 6.023 x 1023 atoms So, in 3.05 moles there are 18.37 x 1023 atoms
