hi, all. I am facing problem in the calculation to prepare minimal media (composition below) that contain 10 ppm chromium. I want to prepare 100 ml minimal media contained 10 ppm of chromium. can anyone help me to do that?
composition of minimal media
DI water ~80ml
Di water ~20ml
if I add 10 ppm chromium in solution A, is my media already contain 10 ppm of chromium?
thanks in advance.
