0.1M is 1/10 molar whereas 1mM is 1 millimolar and thus 1/1000 molar. There is thus a 1:100 dilution. So 10:1000 would be the same.
To a 1000ml volumetric flask, pipete 10mls of 0.1M EDTA solution. Make up to the mark with deionized water. Mix and shake and you will have 1000mls of 1mM EDTA solution.
100ccx 0.1x292.25/1000=2/29g EDTA for 100cc water
EDTA is an ion with 4- charge so is soluble in water.
for prepare 1mM DPPH radical solution: DPPH Molecular weight: C18H12N5O6 = 394g DPPH 1mM = 394/1000= 0.394g/L
0,4 g NaOH + 1000 ml H2O
EDTA has a molecular weigh of 292.24g/mol. So if you want to make 1 litre for example of 0.5M EDTA, you'd weigh out 292.24*0.5 or 146.12g of EDTA and dissolve and fill to 1 litre with solvent
You dilute it 1:10, then you take 1 part of that solution and mix it with 9 parts of the diluent. That will make the 1:100 dilution you need, incl. prevention of pipette inaccuracy.
100ccx 0.1x292.25/1000=2/29g EDTA for 100cc water
EDTA is an ion with 4- charge so is soluble in water.
18.6gms dissolved in 1000ml distilled water

10 mM Tris pH 7.5 and 1mM EDTA pH 8.0 For 1 L : 10 mL of 1M Tris-Cl pH 7.5 and 2 mL of 500mM EDTA pH 8.0
EDTA has a molecular weigh of 292.24g/mol. So if you want to make 1 litre for example of 0.5M EDTA, you'd weigh out 292.24*0.5 or 146.12g of EDTA and dissolve and fill to 1 litre with solvent
1 cm is .01m so 600cm*.01m = 6m =] -ray
.01m = 1cm
5mM = 0.005 moles 100 mL = 0.1 Liters Molarity = moles of solute/Liters of solution 0.005 M EDTA = X moles/0.1 Liters = 0.0005 moles EDTA =_____________ Now, look up the molecular formula for EDTA and find how many grams needed to add to your 100 mL.
