This is equivalent to asking "How many eggs are in 1 dozen brown eggs?", the answer is one dozen.
Both the mole and the dozen are unit less quantities that could (in principle) be applied to anything, however the mole is a much much larger quantity than the dozen (by 22 orders of magnitude). One could even talk about having a mole of eggs... but there wouldn't be enough space on earth to keep them!

How many atoms make 1 pound?
1 mole of anything always contains 6.022*1022 things; therefore, 1 mole contains 6.022*1022 atoms.
How many moles are in one molecule?
MolesOne mole is 6.02 × 1023 of anything. One mole of atoms is 6.02 × 1023 atoms, one mole of rice is 6.02 × 1023 grains, one mole of shoes is 6.02 × 1023 shoes. You get the picture? One mole of molecules is 6.02 × 1023 molecules.
How many atoms are in 0.5 mole of Ar?
6.226 x 10^28 atoms of Nitrogen approximately mole = 6.226 X 10^28 objects Nitrogen exists as a diatomic molecule, so in 0.5 moles of diatomic nitrogen gas there are exactly 1 moles worth of molecules, therefore the number of atoms in 0.5 moles of nitrogen gas is equal to the value of the mole which is approximately 6.226 x 10 ^ 28 atoms
How many atoms are in a sample of 1.83 moles of potassium (K) atoms?
Okay, a mole of potassium perchlorate contains 6.02x1023 formula units of potassium perchlorate, but you're asking about individual atoms. So, let's look at the formula: KClO3. That's 1 potassium, 1 chlorine, and 3 oxygens, for a total of 5 atoms per formula unit. Now, multiple 5 by Avogadro's number above, to get 30.1x1023, which simplifies to 3.01x1024 atoms.
How many molecules are in 3.5grams of H2O?
There are 23 atoms in 6.0 g of water. Using this formula (6 g H2O)(1 mol H2O / 18 g H2O) = 1/3 mol H2O (1/3 mol H2O)(2 mol H / 1 mol H2O)(6.022 x 10^23 atoms H / 1 mol H) = 4.0 x 10 therefore 23 atoms.
How many iron atoms are present in a 23.0 g iron block?
1 mole Fe = 55.845g Fe 1 mole Fe = 6.022 x 1023 atoms Fe 23.0g Fe x (1 mole Fe/55.845g Fe) x (6.022 x 1023 atoms Fe/1 mole Fe) = 2.40 x 1023 atoms Fe
How many moles of iron is 5.98x1024 atoms 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
How many iron atoms are contained in 354 g of iron?
354 g Fe x 1 mole Fe/55.85 g Fe x 6.02x10^23 atoms Fe/mole Fe = 3.82x10^24 atoms of iron
How many atoms does iron filings have?
It depends on the mass of iron. 1 mole Fe = 55.845g = 6.022 x 1023 atoms Fe
How many atoms in 10 mg of iron?
10 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 1023/1 mole Fe) = 1.1 X 1020 atoms of iron ===================

How many atoms are there in 1 cm3 of iron?
The density of iron, Fe, at room temperature is 7.874 g/cm3. So 1cm3 of iron has a mass of 7.874g. 1 mole iron = 55.845g Fe = 6.022 x 1023 atoms Fe. 7.874g Fe x 6.022 x 1023 atoms Fe/55.845g Fe = 8.491 x 1022 atoms Fe
How many iron atoms would there be in 169 milligrams of iron?
169 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 10^23/1 mole Fe) = 1.82 X 10^21 atoms of iron --------------------------------------
What is the total number of atoms in 1 mole of Fe?
1 mole of any substance contains 6.02 x 10^23 atoms It's avogadro's number :)
How many moles are in 1.01e23 F atoms?
1 mole F atoms = 6.022 x 1023 F atoms 1.01 x 1023 F atoms x (1mol F atoms/6.022 x 1023 Fe atoms) = 0.168mol Fe
How many atoms are in 1.45 g of Ag?
Convert 1 gram Fe to moles by dividing by molecular weight, in this case: 55.8 g/mol.So 1 gram = 1/55.8 or 0.0179 moles of Fe. 1 mole of any substance contains Avogadro's number of atoms or 6.022e23. So multiply 0.0179 by 6.022e23 to get:1.079*1022 atoms of Fe (iron)
