Forum rules
Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

% to ppm

I have one solution that is 5.25% concentration - i need to dilute it to 100 ppm concentration - volume is not important - smaller the better - basically, how much of the 5.25% solution would I add to 100 ml water to make 100 ppm solution. Please help - my brain exploded! Thanks!

5.25% is 52500 ppm; you need to dilute it 525:1. I doubt you can measure anything less than 1 mL with any accuracy. With a small graduate, I would measure out 1 ml, put it in a larger graduate and add water to dilute it to 525 mL.

If you can measure smaller amounts well, measure out 0.2 mL and dilute it to 105 mL
