Problem

Calculate the concentration of an oxalic acid (H ₂C₂O₄) solution when 73.4 mL of water is added to 31.5 mL of a 3.03 M oxalic acid solution?

A. 10.1 M
B. 1.30 M
C. 0.910 M
D. 2.12 M
E. 2.28 M

Solution

We are being asked to find the final concentration of the oxalic acid solution when 73.4 mL of water is added to the solution. When we are adding water (or solvent) to a solution to decrease its concentration, we are diluting the solution.

When dealing with dilution we will use the following equation:
