Question
If you were making a 1:10 dilution of a 100mM NaCl solution what will be its final concentration?
Solution
A 1:10 dilution means that 1 part of the original solution is diluted with 9 parts of diluent.
Here's how you calculate the final concentration:
- Start with the initial concentration of the solution, which is 100mM.
- Divide the initial concentration by the dilution factor. The dilution factor here is 10 (1 part solution + 9 parts diluent = 10 parts total).
- So, 100mM divided by 10 equals 10mM.
Therefore, the final concentration of the NaCl solution after a 1:10 dilution would be 10mM.

What is the concentration of NaCl, in moldm−3, when 10.0 cm3 of 0.200 moldm−3 NaCl solution is added to 30.0 cm3 of 0.600 moldm−3 NaCl solution?
A student performed a serial dilution involving a 1.00 mol dm–3 solution of NaCl. To do this, the student took 10 cm3 of that solution, added it to a 100 cm3 volumetric flask and diluted with water up to 100 cm3 to create dilution #1. The student then took 10 cm3 of dilution #1, added it to a 100 cm3 volumetric flask and diluted with water up to 100 cm3 to create dilution #2. The student repeated this process 3 more times to get dilution #5.Calculate the concentration of dilution #5 in g cm–3.
