Please type your subject in the School Subject box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.
Write and balance the equation.
4Fe + 3O2 ==> 2Fe2O3
Convert 16.7 g Fe to moles. moles = grams/molar mass
Using the coefficients in the balanced equation, convert moles Fe to moles Fe2O3.
Finally, convert moles Fe2O3 to grams. g = moles x molar mass.
