How many Fe atoms are in 0.25 moles of Fe?
To determine the number of moles of Fe that can be made from 25 moles of Fe2O3, you need to write the balanced chemical equation for producing O2 from Fe2O3. 2Fe2O3 = 4Fe + 3O2, which means that 2 moles of Fe2O3 will produce 4 moles of Fe and 3 moles of O2 . Set up a proportion. 3 moles of O2 ÷ 2 moles of Fe2O3 = x moles of O2 ÷ 25 moles of Fe2O3 Cross multiply and divide. 3 moles of O2 * 25 moles of Fe2O3 ÷ 2 moles of Fe2O3 = 37.5 moles of O2 produced.
How many atoms are in 5.0 mole of Fe?
There are 3.01 x 10^24 atoms in 5.0 moles of Fe. This is calculated using Avogadro's number (6.022 x 10^23 atoms/mol) multiplied by the number of moles.
How many moles of iron are present in 3.15E24 atoms of iron?
1,495
How many atoms are there in 55.8 grams of Fe?
To find the number of atoms in 55.8 grams of Fe, you need to first calculate the moles of Fe using the molar mass (55.85 g/mol). Then you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms.
How many atoms in iron oxide Fe2O3?
In one molecule of iron (III) oxide (Fe2O3), there are a total of 5 atoms: 2 iron (Fe) atoms and 3 oxygen (O) atoms.
How many atoms are present in 4.80 moles of Fe?
To find the number of atoms in 4.80 moles of Fe, you need to use Avogadro's number, which is 6.022 x 10^23 atoms/mol. So, 4.80 moles of Fe would contain: 4.80 moles x 6.022 x 10^23 atoms/mol = 2.89 x 10^24 atoms of Fe.
How many atoms are present in 4.80 mole of Fe?
4,80 moles of Fe contain 28,9062761136.10e23 atoms.
How many atoms are present in 400g Iron?
To determine the number of atoms present in 400g of iron, we need to first calculate the number of moles of iron using its molar mass (55.85 g/mol). Next, we can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. Finally, multiply the number of moles by Avogadro's number to find the total number of atoms in 400g of iron.
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 number of Fe atoms and what amount of Fe atoms are in 500 g of Fe?

How many atoms of Fe are in 12.5 g Fe?
To determine the number of atoms in 12.5 g of Fe, you need to first calculate the number of moles of Fe using its molar mass (55.84 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
How many atoms are in 10g of Fe?
To determine the number of atoms in 10g of Fe, you first need to calculate the number of moles of Fe using its molar mass (55.85 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in those moles of Fe. Finally, multiply the number of moles by Avogadro's number to get the total number of atoms in 10g of Fe.
How many Fe atoms are in 0.25 moles of Fe?
To determine the number of moles of Fe that can be made from 25 moles of Fe2O3, you need to write the balanced chemical equation for producing O2 from Fe2O3. 2Fe2O3 = 4Fe + 3O2, which means that 2 moles of Fe2O3 will produce 4 moles of Fe and 3 moles of O2 . Set up a proportion. 3 moles of O2 ÷ 2 moles of Fe2O3 = x moles of O2 ÷ 25 moles of Fe2O3 Cross multiply and divide. 3 moles of O2 * 25 moles of Fe2O3 ÷ 2 moles of Fe2O3 = 37.5 moles of O2 produced.
How many atoms are in 30 moles of iron?
A mole is 6.022×1023 of anything, including atoms. So to determine the number of atoms are in 30 moles of iron, you multiply the number of moles times 6.022×1023. 30mol Fe x 6.022×1023 atoms Fe/1mol Fe = 1.8066×1025atoms Fe When corrected for significant figures, the answer is 2×1025atoms Fe. Note: the number following the 10 in the large numbers is the exponent on the 10 and should be written as superscripts, but that is not supported at the moment.
How many atoms are found in 600 grams of iron?
To determine the number of atoms in 600 grams of iron, you would first need to calculate the number of moles of iron using the molar mass of iron (55.85 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
How many atoms are in 5.0 mole of Fe?
There are 3.01 x 10^24 atoms in 5.0 moles of Fe. This is calculated using Avogadro's number (6.022 x 10^23 atoms/mol) multiplied by the number of moles.
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.
