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.
