Best ResponseYou've already chosen the best response.0novice in chem,well i just looked at the atom it has 2 moles and Fe2O3 has 1 so yeah

Best ResponseYou've already chosen the best response.1to figure out which is limiting you want to to take Grams of reactant >mols of reactant>moles of product with both... which ever can make the least amount of moles of product is your limiting reactant

Best ResponseYou've already chosen the best response.1alright and then there is 2 aluminum molecules per 2 iron

Best ResponseYou've already chosen the best response.1so you cna make 9.16 moles of iron with 9.16 moles of aluminum

Best ResponseYou've already chosen the best response.0wait 9.6 was error i took wrong mass Al n=5.7

Best ResponseYou've already chosen the best response.1o wait nvm 5.7 molecules of aluminum can make 5.7 molecules for iron

Best ResponseYou've already chosen the best response.1however per each iron oxide molecule you can make 2 iron oxide molecules

Best ResponseYou've already chosen the best response.1so multiply 4.5*2 =9 moles of iron.... since you can only make 5.7 moles with the aluminum , Al is your limiting reagent

Best ResponseYou've already chosen the best response.1now just change 5.7 moles of Fe to grams

Best ResponseYou've already chosen the best response.1so that would be your answer

Best ResponseYou've already chosen the best response.0so cant we say there 2Al n=5.7 but 2 moles n=2(5.7)

Best ResponseYou've already chosen the best response.0the periodic table i am using says atomic weight =Al M=26g/mol is this the right thing to use as M
