0.0845 moles of tungsten is equal to 0,50887.10e23.
5,82 x 1023 atoms of tungsten equal 0,966 moles.
Not many! ( how do you people keep coming up with fractional atoms? ) 4.8 atoms tungsten (1 mole tungsten atoms/6.022 X 10^23) = 8.0 X 10^-24 moles tungsten atoms
It seems there might be a misunderstanding, as you can't have a fraction of an atom in the physical sense. Atoms are discrete particles, so you can have whole numbers of tungsten atoms (e.g., 1, 2, 3, etc.), but not 2.251022. If you meant to ask about a quantity of tungsten in terms of moles, you could convert it using Avogadro's number (approximately (6.022 \times 10^{23}) atoms per mole) to find how many moles correspond to that number of atoms.
The mass of 15 moles of tungsten is 2.757,6 g.
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6

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

1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
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.
4,37.10e-18 C atoms are equivalent to 7,25.10e-6 moles.
In Ca(HCO3)2, there are 2 moles of carbonate ions (CO3^2-), each containing 3 atoms. So there are 6 atoms in 1 molecule of Ca(HCO3)2. Therefore, in 4 moles of Ca(HCO3)2, there are 4 x 6 = 24 moles of atoms.
4,80 moles of Fe contain 28,9062761136.10e23 atoms.
