Dilution
« on: May 04, 2023, 04:32:35 PM »
Hi guys. I need help calculating how to make up a solution. I’m hoping someone can help.

If I have solution A at 0.8ppm and solution B at 25000ppm. How do I make a 500ppm solution out of the two in 100ml.

Thanks in advance.

Cross rule

25000         499.2
            500
0.8           24500
________________
                 24999.2 equal 100 ml



Take 2 ml of 25000 ppm and 98 ml of 0.8 ppm.
