i got this formula

[itex]
2Fe +3O_2 -> 2FeO_3
[/itex]

how many grams of Fe and litters of oxigen do i need
in order to get 0.5 kilogram of

[itex]
Fe_2O_3
[/itex]

i can find how much grams weighs each mole of each molecule?

i don't know how to do the rest

??

ok i understand
3 moles of
[itex]
O_2
[/itex]
can react at most with 2 moles of Fehow do i transform the volume of a gas into grams?
 
  • #4
pV=nRT, ideal gas equation.
 
  • #5
ok by pst 22.4 litters for every mole of gas
i can find the weight of each mole
what now?
