so I have this problem and I don't know what numbers to multiple and whatnot. Can someone help me?
This is the problem:
4000 g Fe2O3* 1mole Fe2O3/159.68 gFe2O3* 3mole CO2/1mole Fe2O3
Indicate your subject in the "School Subject" box, so those with expertise in the area will respond to the question.
From what i see your trying to convert 4000 grams of fe203 to moles, and then multiply the find the amount of fe203 in 3 moles of co2. So your answer would be
= 75.2 mole of co2 .
now, find how many moles of H2O are there in 45.4 grams H2O?
