For example, so my liquid is 0.897 g/cm3 is 0.897 g/ml. So I need 100 ppm. If I take 1.02 ml and put in 998.98 ml solvent which is 100 ppm. Am I right? or If I take 0.51 ml and 499.49 ml solvent, so it is 100 ppm. am I right?

Hi. It's in liquid form. The FW is 142.2 and relative density is 0.897 g/cm3 which is 897 kg/m3. So do I need to take 10 µl cis-3-hexenyl acetate and 990 µl solvent to make 100 ppm

Thank you
