9,003 x 1023 atoms of iron correspond to 1,495 moles.
1 mole of iron atoms has the greatest mass - 55,845 g.
The number of iron moles is x(atoms)/6,022140857.10e23.
A lot!! 850 moles iron (6.022 X 10^23/1 mole Fe) = 5.12 X 10^26 atoms of iron
You need to know what elements the coin is made up of (ie. what percent is iron and what percent is copper). You'd then need to weigh the coin out. If you wanted to know how many iron atoms there are, then you'd calculate how much iron there is and convert that to moles and then to atoms using avogadro's number.
Molar mass of iron is 56g. Given mass of iron= 112g No. of moles = Given mass/Molar Mass => 112g/56g= 2 moles
9,003 x 1023 atoms of iron correspond to 1,495 moles.
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
5.0x10^25 * (1 mol / 6.022x10^23 atoms) = 83 moles of iron.
0.4965 moles rounded to 4 significant figures
1 mole of iron atoms has the greatest mass - 55,845 g.
The answer is 3,587 moles.
Divide it by Avogadro constant.There are 0.0088 moles
The number of iron moles is x(atoms)/6,022140857.10e23.
Fe, or iron, has a molar mass of 55.845 grams per mole. This means that 0.2 moles is equal to 11.2 grams of iron.
1 mole of atoms of any element is 6.022 x 1023 atoms. 1 mole of Fe = 6.022 x 1023 atoms Fe 5.98 x 1024 atoms Fe x (1mol Fe/6.022x1023 atoms Fe) = 9.93 moles Fe
5.22 x 10 to the power of 22 iron atoms is equivalent to 0,087 moles.
