The atomic weight of iron is 55,845.
This element has 26 neutrons, so its atomic number would be 26. Given an approximate atomic mass of 48 amu, this corresponds to the element iron (Fe).
What is the chemical 'FE'. Do you mean 'Fe'. If so to answer your question . The molar mass of iron (Fe) is 55.845
FeO is 50 mole % Fe and 50 mole % O FeO is 77.73 mass % Fe and 22.27 mass % O mass fraction X = molar mass X / (total molar mass of compound) mass % Fe = [atomic mass Fe] / ([atomic mass Fe] + [atomic mass O])
The atomic mass of iron (Fe) is approximately 55.85 grams per mole.
For this you need the atomic mass of Fe. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel..410 grams Fe / (55.9 grams) = .00733 moles Fe
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.
The element with an atomic mass of 55.85 amu is Iron (Fe).
These values are similar.
To determine the mass of iron needed to react with 16.0g of sulfur, first balance the chemical equation: 8 Fe + FeS2 -> 9 FeS. As each Fe reacts with 1/2 S, the molar ratio is 8:1/2. Calculate the molar mass of Fe and FeS to convert between moles and grams. Then use the molar ratio to find the mass of Fe needed: (16.0g S)*(8 mol Fe / 1 mol S) * (55.85 g Fe / 1 mol Fe) = 711.2 g Fe.
To calculate the Fe content in FeO, you need to consider that Fe accounts for about 71.85% of the FeO compound's molecular weight. For Fe2O3, each Fe atom accounts for about 69.94% of the compound's molecular weight. After determining the molecular weight of FeO and Fe2O3, you can find the Fe content by multiplying the molecular weight of Fe by the appropriate percentage.
Iron (Fe) has an atomic mass of 55.8.
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.
