Question

Iron reacts with oxygen to form rust according to the equation: 2 Fe + 3 O2 --> 2 Fe2O3

If you react 60,5 moles of oxygen gas, how many moles of rust can you form?

Answer 1

Answer: 40.3

Step-by-step explanation:

In the reaction, we see that for every 3 moles of oxygen gas consumed, 2 moles of rust are formed.

So this means that if 60.5 moles of oxygen gas are consumed, then (60.5/3)(2)=40.3 moles of rust can be formed.
