Please suggest me a correct method of dilution of solutions to convert ppm to ppb.
Let suppose I have 0.05 mg/ml solution, it has 50 ppm and I want to convert into different ppb solutions like 50, 100, 200 etc ppb.

Dear Arnand,
1ppm = 1 part per million = 10-6
1ppb = 1 part per billion = 10-9
Thus 1ppm = 1000ppb.
So e.g. 50ppm = 50*1000ppb = 50000ppb
