<u>Answer:</u> The atomic symbol of the given element is 
<u>Explanation:</u>
The general isotopic representation of an element is given as: 
where,
Z represents the atomic number of the element
A represents the mass number of the element
X represents the symbol of an element
For the given isotope: 130-iodine
Mass number = 130
Atomic number = 53
Hence, the atomic symbol of the given element is
8.04 mL.
<h3>Explanation</h3>

Note the unit:
.
.
How many moles of HCl?
As seen in the equation, HCl and NaOH reacts at a 1:1 ratio.
.
How many mL of HCl?
.
The property of a solution which remain the same after it is diluted is THE AMOUNT OF SOLUTE.
Dilution is the process of adding solvent to a solution. This action decreases the concentration of the solute in the solution. When a solution is diluted, the amount of solvent increase, the total volume increases, the concentration decreases, but the amount of solute stays the same.
