Calculate the number of iron atoms in a sample of iron(III) oxide . Be sure your answer has a unit symbol if necessary, and round it to significant digits.
Added by Todd M.
Step 1
The molar mass of Fe = 55.85 g/mol The molar mass of O = 16.00 g/mol Molar mass of Fe2O3 = 2(55.85) + 3(16.00) = 159.70 g/mol Show more…
