Mass of iron chloride (FeCl₂) : 22.68 g
<h3>Further explanation</h3>Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison
With this law, we can calculate how many grams an element is needed to make a compound with a certain mass, as desired
<h3 />The iron ions in 50 g mixture :
3.6 moles required when each quantity of reactant completely reacts.
The ratio of the mole quantities of any two compounds present in a balanced chemical reaction is known as the mole ratio. A reaction's product yield can be predicted using mole ratios, as can the amount of reactant required to produce a specific amount of result.
The balanced chemical equation is :
(l) →
(g) +
(g)
Given is = 2.6 mol
As we see, 3 moles of reacts with 4 moles of
.
Therefore,
n( ) = n(
) ×
n( ) =
n( ) = 3.6 moles.
Therefores, 3.6 moles required when each quantity of reactant completely reacts.
