Calculate the concentration of F- using M1V1=M2V2 by using the
following procedure:
0.027g of NaF was used to make 250.00 ml of 50 ppm F- stock
solution. Then you remove a 25.00 ml aliquot and diluted in a 250
ml flask. After mixing, you transferred 10, 20, 30, 40, 50 ml
aliquots of the resulting 5 ppm solution to 100 ml flask.
If you could just show a detailed example of the 10 ml aliquot,
then I can use that to figure out the rest. Please and thank
you!
