Hello!
To know how many moles of iron can be recovered from 100 kg of Fe₃O₄ we'll need to use the
molar mass of Fe₃O₄ and apply the conversion factor to go from kg of Fe₃O₄ to moles of Fe in the following way:
So, theoretically, one could recover
1192,68 moles of Fe from 100 kg of Fe₃O₄
Have a nice day!

Answer:
Hello, Your answer is False
Explanation:
<em>Because its False when a Heat is absorbed by the system from the surroundings. exothermic: Heat is released by the system into the surroundings. law of conservation of energy: In any physical or chemical process, energy is neither created nor destroyed. Hope That Helps!</em>
<span>Zn3P2O8
We have the ratio 0.21 : 0.14 : 0.56 and we want to come up with a ratio of simple integers, so first divide all the numbers by the smallest which is 0.14, getting 1.5 : 1 : 4, The 1 and 4 look OK, but obviously the 1.5 isn't anywhere close to an integer. But that can be corrected easily by multiplying all the numbers again by 2, giving 3 : 2 : 8. So the empirical formula is Zn3P2O8.</span>
Answer:
224.28 g of W, are in 1.22 moles of it
Explanation:
This can be made by a rule of three:
1 mol of Tungsten (W) weighs 183.84 grams
1.22 mol of W, would weigh 224.28 g (1.22 . 183.84)
