An exothermic reactions experiment and endothermic reactions experiment.
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:
The concentration is
Explanation:
From the question we are told that
The absorbance is
The length is
Generally absorbance is mathematically represented as
where is the molar absorptivity of FeSCN2 with a value
and is the equilibrium concentration of FeSCN2
So
substituting values
Answer:
1.24*10^6=1.24*1000000=1240000
6.2*10^-3=6.2*0.001=0.0062
