gravimetric stoichiomerty..... eh? HELP

nic.harv

calculate the mass of iron(III) oxide (rust) produced by the reaction of 500g of iron with oxygen from the air

so i have no idea what do do here, my teacher sucks monkeys balls.

so i thought to do the mass of iron(III) oxide divided by the 500g but i know thats wrong. PLEASE HELP ME! I actually have no idea of what im suppose to do.

Start with the reaction equation. And check these pages:

How to read reaction equation.

Stoichiometric calculations using ratio & proportions.

Stoichiometric calculations using dimensional analysis.
