Use the Avogadro constant

2.50 x 10^20 atoms Fe x ( 1 mol Fe / 6.023 x 10^23 atoms) =4.15 x 10^-4 mol

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 iron atoms are present in a 23.0 g iron block?

To determine the number of iron atoms in a 23.0 g iron block, you would first calculate the number of moles of iron using the molar mass of iron (55.85 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of iron to atoms.


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 ===================


What number of Fe atoms and what amount of Fe atoms are in 500 g of Fe?

Known/Given:1 mole of Fe = 55.845g Fe (its atomic weight in grams)1 mole of Fe = 6.022 x 1023 atoms Fe (from Avogadro's number)Convert grams Fe to moles Fe.600.0g Fe x 1mol Fe/55.845g Fe = 10.74mol FeConvert moles Fe to atoms Fe.10.74mol Fe x 6.022 x 1023atoms Fe/1mol Fe = 6.468 x 1024atoms Fe


How many moles of iron is 5.98x1024 atoms of iron?

To find the number of moles, you need to divide the number of atoms by Avogadro's number, which is about 6.022 x 10^23 atoms/mol. So, 5.98 x 10^24 atoms of iron would be approximately 9.93 moles 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 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 are contained in 354 g of iron?

There are approximately 3.25 x 10^24 iron atoms in 354 g of iron. This calculation is done by converting the mass of iron to moles using the molar mass of iron, and then using Avogadro's number to convert moles to atoms.


How much does 1 mole of Fe weigh in grams?

Use stoichometry to figure this out. 1 mole Fe * 56 g Fe ...............1 mole Fe


Does 1 mole of hydrogen atoms equals 1 mole of helium atoms?

No, 1 mole of hydrogen atoms does not equal 1 mole of helium atoms. One mole of any element contains Avogadro's number of atoms (6.022 x 10^23), so 1 mole of hydrogen atoms would have that many hydrogen atoms, while 1 mole of helium atoms would have that many helium atoms.


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 --------------------------------------
