how many moles of fe are present in 30g of rust?
Not understandable
To determine the number of moles of Fe (iron) in 30g of rust, we need to follow the steps below:
Step 1: Find the molar mass of Fe
The molar mass of Fe (iron) can be found on the periodic table, which is approximately 55.85 g/mol.
Step 2: Convert grams to moles using the molar mass
To convert grams of Fe to moles, divide the given mass by the molar mass.
Number of moles = Mass (g) / Molar mass (g/mol)
In this case, we have:
Number of moles of Fe = 30g / 55.85 g/mol
Calculating the value:
Number of moles of Fe = 0.536 moles
Therefore, there are approximately 0.536 moles of Fe present in 30g of rust.
You need to find the caps key and use it. fe isn't anything. CO, Co, co have different meanings.
Rust is one of those complicated formulas. If we assume the formula is Fe2O3.
mols Fe2O3 = 30/molar mass Fe2O3 = ?
Then 2 x that = mols Fe.
