Answer:
The freezing point depression ∆T = KF·m where KF is the molal freezing point depression constant and m is the molality of the solute. Rearrangement gives: mol solute = (m) x (kg solvent) where kg of solvent is the mass of the solvent (lauric acid) in the mixture. This gives the moles of the solute.

Explanation:
You are not putting the equation to balance. I found a question which is pretty the same as this one and put the following reaction:
H₂ + O₂ ------> H₂O
If you have a different equation please post again the question.
According to the above reaction, we can say that it's not balanced.
The reason is because in the reactants we have 2 atoms of hydrogen and oxygen, but in the products, we only have 1 atom of oxygen. so both sides do not have the same number of atoms.
To balance, we need to put a number in the product or reactant as coefficient in order to balance the whole reaction. In this case, as Oxygen is unbalanced, I will put a 2 in the products to balance the oxygen:
H₂ + O₂ ------> 2H₂O
But putting this 2 will unbalance the hydrogen in the products. We now have 4 atoms of hydrogen. What should we do now?, yes, we put a 2 in the reactants to balance the hydrogen, and then, the whole equation is balanced.
2H₂ + O₂ ------> 2H₂O
Hope this helps
Explanation:
1)Mass of CO when 210.3 g of Fe produced.
Number of moles of in 210.3 g=
According to reaction, 2 moles of Fe are obtained from 3 moles of CO, then 3.76 moles of Fe will be obtained from : of CO that is 5.64 moles.
Mass of CO in 5.64 moles =
2)Mass of CO when 209.7 g of Fe produced.
Number of moles of in 209.7 g=
According to reaction, 2 moles of Fe are obtained from 3 moles of CO, then 3.75 moles of Fe will be obtained from : of CO that is 5.625 moles.
Mass of CO in 5.625 moles =
