<u>Answer:</u> The volume of solution required is 0.0275 L.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of copper = 4.24 g
Molar mass of copper = 63.55 g/mol
Putting values in above equation, we get:
The chemical equation for the reaction of potassium dichromate and copper follows:
By Stoichiometry of the reaction:
3 moles of copper reacts with 1 mole of potassium dichromate.
So, 0.067 moles of copper will react with = of potassium dichromate
To calculate the volume of potassium dichromate, we use the equation:
We are given:
Moles of potassium dichromate = 0.022 mol
Molarity of solution = 0.800 M
Putting values in above equation, we get:
Hence, the volume of solution required is 0.0275 L.
