Dear student
The formula of rist is is approximately Fe2O3•32H2O
Rust is apparently a hydrated form of iron(III)oxide.
Hope this will help
Good Luck

ANSWER
Iron metal does not burn in dry air even on strong heating. In moist air iron is slowly oxidised to give rust (iron oxide).
4Fe+3O2→2Fe2O3+nH2O→Fe2O3.nH2O(Rust)
