Question
Asked Sep 27, 2019

A 57.0 mL aliquot of a 1.30 M solution is diluted to a total volume of 208 mL. A 104 mL portion of that solution is diluted by adding 173 mL of water. What is the final concentration? Assume the volumes are additive.

Step 1

Dilution Factor: “It is the ratio of total volume to volume of solute” or “It is the ratio of concentration of concentrated solution to concentration of dilute solution”.

It essentially indicates the factor by which concentration of an initial solution decreased upon dilution.
