Answer: The final molarity of the diluted oxalic acid solution is 0.0032 M
Explanation:
Molarity: It is defined as the number of moles of solute present per liter of the solution.
Formula used :

where,
n= moles of solute
Moles=
= volume of solution in ml

To calculate the final molarity of the diluted oxalic acid solution

where,
are the molarity and volume of concentrated oxalic acid solution.
are the molarity and volume of diluted oxalic acid solution.
We are given:

Putting values in above equation, we get:

Thus the final molarity of the diluted oxalic acid solution is 0.0032 M
