The molecular weight of the EDTA will vary depending on chemical makeup - regardless, the solution you have is probably less than 10% already. EDTA tri-sodium salt with MW 358 at 0.25 M is 89.5 g per liter or 8.95 g per 100 ml or 8.95%.

I need to make 10% EDTA. Do I just dilute it 1/10 with DI water? Thanks Kimberly C. Tuttle HT (ASCP) Pathology Biorepository and Research Core University of Maryland Room NBW58, UMMC 22 S.
