I have a bottle of EDTA (not disodium, F.W. 292.25. How do I prepare 10 mmol/L EDTA?

Hopefully, my pH should be around 7.6.

Answer:
1mol of EDTA = 292.25g EDTA
292.25mg = 1mmol

10mmol = 2922.5mg EDTA

10mM solution = 2922.5mgEDTA dissolve in 1L
Sounds so.
convert mmol to grams, miligrams.. whatever is more convenient. put it into a volume flask. and fill it until the solution is a liter.
