Answer:
Molar concentration of solution = 0.0056 moles / liter
Explanation:
Looking at the chemical reaction we realize that the precipitate, formed by adding the iron powder, is cooper.
Then for finding the number of moles of precipitated copper:
From the chemical reaction we deduce that moles of Cu equals to moles of in the initial solution.
So molar concentration is defined as:
