TheThe volume should be added in dilute is 3.24L.
<h3>What is Molarity? </h3>
Molarity is the amount of a substance in a certain volume of solution. It is defined as the moles of solute per litre of a solution.
Molarity = no of moles / Volume (L)
Where the unit of Molarity is M or moles/ L .
We have given here ,
Molarity→5M
Volume →50 ml
Vol2→25.0 ml
weight of the K I is 3.05 g and molar mass of KI is 166 g/ mol.
M1V1=M2V2
M2= no of moles of KI / Volume
M2 = 3.05×1000/ 25×166
M2→ 0.73M
V2→5×50×1000/ 0.73
V2→ 3.24 L
The volume of the solution will be 3.24 L.

The melting point (or, rarely, liquefaction point) of a solid is the temperature at which it changes state from solid to liquid at atmospheric pressure. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at standard pressure.
Molarity is defined as number of moles of solute in 1 L of solution.
Here, 0.1025 g of Cu is reacted with 35 mL of HNO_{3} to produced Cu^{2+} ions.
The balanced reaction will be as follows:
Cu+3HNO_{3}\rightarrow Cu(NO_{3})_{2}+NO_{2}+H_{2}O
From the above reaction, 1 mole of Cu produces 1 mole of Cu^{2+}, convert the mass of Cu into number of moles as follows:
n=\frac{m}{M}
molar mass of Cu is 63.55 g/mol thus,
n=\frac{0.1025 g}{63.55 g/mol}=0.0016 mol
Now, total molarity of solution, after addition of water is 200 mL or 0.2 L can be calculated as follows:
M=\frac{n}{V}=\frac{0.0016 mol}{0.2 L}=0.008 mol/L=0.008 M
Thus, molarity of Cu^{2+} is 0.008 M.
