To find the number of moles, divide the given mass of iron (Fe) by its molar mass. The molar mass of iron is approximately 55.85 g/mol.
Number of moles = Mass (g) / Molar mass (g/mol) Number of moles = 200 g / 55.85 g/mol Number of moles = 3.58 mol
Therefore, 200g of Fe is approximately 3.58 moles.
To determine the number of moles in 200g of Fe (iron), you need to first find the molar mass of Fe, which is approximately 55.85 g/mol. Next, you divide the given mass by the molar mass to find the number of moles. Therefore, 200g of Fe is equal to approximately 3.58 moles (200g / 55.85 g/mol ≈ 3.58 mol).
Oh, dude, so like, the molar mass of Fe is around 55.85 g/mol. So, if you have 200g of Fe, you just divide that by the molar mass to get the number of moles. That's like around 3.58 moles of iron. Easy peasy, right?
For this you need the atomic (molecular) mass of FeCl3. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. FeCl3=162.4 grams
.200 moles FeCl3 × (162.4 grams) = 32.5 grams FeCl3
200 grams Fe (1 mole Fe/55.85 grams)
= 3.58 moles of iron

To find the number of moles in 23 g of Fe, first find the molar mass of Fe by looking up the atomic weight on the periodic table. Fe has a molar mass of approximately 55.85 g/mol. Divide the given mass by the molar mass to find the number of moles: 23 g Fe / 55.85 g/mol = approximately 0.41 moles of Fe.
To find the number of moles of Fe in Fe2O3, first calculate the molar mass of Fe2O3 and O. Then, determine the number of moles of O in the sample. Finally, you can use the stoichiometry of Fe2O3 to find the moles of Fe present. Alternatively, if you know the molar mass of just Fe, you can calculate the moles of Fe by dividing the mass of Fe in the sample by its molar mass.
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.
The number of molecules is 12,044280.10e23.
