The molarity of the solution will be 3.45 M
<h3>Further explanation
</h3>
Dilution is the process of adding a solvent to get a more dilute solution.
The moles(n) before and after dilution are the same.
Can be formulated :
M₁V₁=M₂V₂
M₁ = Molarity of the solution before dilution
V₁ = volume of the solution before dilution
M₂ = Molarity of the solution after dilution
V₂ = Molarity volume of the solution after dilution
The initial solution
345 mL of a 2.5 M NaCl solution.
M₁=2.5 M
V₁=345 ml
The solution after boiled :
V₂=250 ml

It has a density lower than 1
It has the same uniform/ appearance so basically they are same but in a different way if that makes sense, they consist of different substances and phrases,
Answer:
adding coefficient
Explanation:
To balance a chemical equation we have to place coefficients as needed in front of the symbols or formulas so the same number of each type of atom occurs in both reactants and products
