The formula for rust can be represented by Fe2O3. How many moles of Fe are present in 24.6 g of the compound?
24.6gFe2O3*molFe2O3/MolarmassFe2O3*2molFe/1molFe2O3= mol Fe
To determine the number of moles of Fe in a compound, you need to use the molar mass of Fe and the mass of the compound.
Step 1: Find the molar mass of Fe.
The molar mass of Fe is the atomic mass of one mole of Fe, which you can find on the periodic table. The atomic mass of Fe is approximately 55.85 g/mol.
Step 2: Calculate the number of moles of Fe.
To find the number of moles of Fe, divide the mass of the compound by the molar mass of Fe.
Number of moles of Fe = Mass of compound / Molar mass of Fe
Given that the mass of the compound is 24.6 g, we can proceed to calculate the number of moles of Fe.
Number of moles of Fe = 24.6 g / 55.85 g/mol
Now, you can use a calculator to perform the division and find the number of moles of Fe in 24.6 g of the compound.
