my question is : How would you make a 1, 3, 5, 7ppm solution from a 100ppm solution?
do i just just this formula: C1V1 = C2V2 to calculate the amount i need?
for example, for 5ppm solution => (5ppm) V1 = (100ppm)V2
so for V1, I just choose my final volume to be whatever i like... like if i was to prepare it in a 100ml volumetric flask, then my V1 would be 100ml.
so I would need (5ppm*100ml) / 100ppm = 5 ml of the stock 100 ppm soln.
Is that correct?
Thank you in advance. =)
