How many moles of fe2o3 are formed when 55.8 g of fe reacts completely with oxygen

Using atomic mass of Fe, 55.8g/mol, and mass of 16.7g, we find number of moles in 4Fe.

16.7/55.8 = 0.30moles of 4Fe

Now, we divide this by 2, as we have 2Fe2O3.

0.30/2 = 0.15moles of 2Fe2O3.

We use the molecular mass of 2Fe2O3 (159.6) multiplied by the number of moles (0.15moles), 159.6x0.15 = 23.94g of 2Fe2O3.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
