1.12g of iron reacts with oxygen to form 1.60g of an oxide of iron. what is the formula of this oxide of iron? I know the answer is Fe2O3.
1.12/ 56 = 0.02
1.60 / 16 = 10
how does this become a ratio?
2) in an experiment 1.226g of Kclo3 was heated. A mass of 0.32g of oxygen gas was collected. What is the oxygen percentage yield fort he experiment??
0.320g / (0.320/16) = 0.02 --> 0.320/0.02 = 6.4 *100
I know its wrong but im confused :/
Should I still go?
