Answer:
0.24V
Explanation:
First we must obtain the ionic strength of the solution I as shown in the image attached. This ionic strength can now be used to obtain the activity coefficient of the ions in solution by substitution of the value of the ionic strength obtained previously and the charge of the ion (Cu2+) into the equation for activity coefficient.
The activity of an ion is defined as the product of its activity coefficient and its concentration. This activity of copper II ion is now substituted into the Nernst equation to obtain the equilibrium potential required in the question.
Answer:
<h3>The answer is 0.4 moles</h3>Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>0.4 moles</h3>Hope this helps you
