The concentration (molarity) of an HBr solution is 0.0107 m.
What is molarity?Molarity is the measure of the concentration of any solute in per unit volume of the solution.
The chemical reaction is
We will calculate the concentration by formula of molar equivalence
Thus, the concentration is 0.0107 m

The concentration of the HBr solution is 0,107M
The chemical reaction between HBr and NaOH is the following:
HBr + NaOH → NaBr + H₂O
To calculate the concentration of the HBr solution, we'll need to apply the following equation (molar equivalence) and clear for the concentration of HBr:
Have a nice day!
