We need to use the following formula
Δ
n= 4 moles
F= constant= 96500C/mol
let's plug in the values.
ΔG= -(4)(96500)(0.24)= -92640 J or -92.6 kJ

Answer : The correct option is, (A) 0.109 M
Solution : Given,
Mass of = 17 g
volume of solution = 974 ml
Molar mass of = 159.609 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of solution.
Formula used :
where,
w = mass of (solute)
M = molar mass of
= volume of solution in liter
Now put all the given values in the above formula, we get the molarity of solution.
Therefore, the molarity of the solution is, 0.109 M
