Answer:

Given the concentration of HCl is 1.5mol/L or 1.5M

The volume of HCl required is --- 80mL

The volume of NaOH is ---- 50mL

What is the concentration of NaOH-- ?

Explanation:

The chemical reaction between NaOH and HCl is shown below:

[tex]NaOH(aq)+HCl(aq)-> NaCl(aq)+H2O(l)\\1mol of NaOH reacts with 1mol. of HCl.\\Number of moles =molarity * volume in L\\At the equivalence point:\\Number of moles of HCl=number of moles of NaOH\\Hence,\\0.08L* 1.5M =0.05L * C \\=>C=\frac{0.08L* 1.5M}{0.05L} \\=>C=2.4M[/tex]

Answer:

The concentration of NaOH required is 2.4M or 2.4mol/L.
