Answer:
The total number of atoms must be the same on both sides in order for it to be a balanced chemical equation.
If not all of the salt has dissolved then the measurement of the concentration at the time is really inaccurate.
<h3>What is concentration?</h3>
The concentration is the amount of substance that is present in solution. We know that we can not measure the concentration unless all of the solute have been dissolved in the solution.
Thus, if not all of the salt has dissolved then the measurement of the concentration at the time is really inaccurate.

Explanation:
Overrides all the other colors of light and green yelow.
<span>molarity is defined as the number of moles of solute in 1 L of solution.
the number of moles of NaOH = mass present / molar mass of NaOH
molar mass of NaOH = 22.99 + 16.00 + 1.008 = 40.00 g/mol
therefore NaOH moles = 29.5 g / 40.00 g/mol = 0.738 mol
the number of NaOH moles in 2.45 L solution - 0.738 mol
therefore number of NaOH moles in 1 L = 0.738 mol / 2.45 L = 0.301 mol/L molarity of NaOH = 0.301 M</span>
