5,82 x 1023 atoms of tungsten equal 0,966 moles.
2 moles equals 8 g of helium or 12.046 x 1023 atoms
1 mole has 6.023 x 1023 atoms So, in 3.05 moles there are 18.37 x 1023 atoms
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.
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
0.94 moles.
5.66 X 1023 atoms of xenon (1 mole Xe/6.022 X 1023) = 0.940 moles of xenon ------------------------------
2 moles equals 8 g of helium or 12.046 x 1023 atoms
1 mole has 6.023 x 1023 atoms So, in 3.05 moles there are 18.37 x 1023 atoms
This is equivalent to 1,4 moles.
1 mole of lithium has 6.023 x 1023 atoms. So 5 moles will have 30.115 x 1023 atoms
6.02 X 1023 particles per mole X .75 moles = 4.52 X 1023 molecules.
9,003 x 1023 atoms of iron correspond to 1,495 moles.
1 mole of an element contains 6.022 X 1023 atomsso in 1.4324 moles no. of atoms is 8.659 X 1023 atoms
A sample of 3,2x10 atoms of nickel is equal to 0,53.10e-23 moles.
Atomic mass: 207.2 grams.455 moles × (6.02 × 1023) = 2.74 × 1023 atoms of lead
