6 How much is the theoretical oxygen demand of 1mM acetate solution?
First write the reaction, get moleculr weight of oxygen and reactant. TOD=(mg/L soln)X(weight of O)/(weight of Reactants)
What is a 1mm of rain event?
1mm of rain is actually water volume of 1lt per 1m2 of surface, 1mm=1lt/1m2 explanation: Simply convert 1lt to 1000 ml. Since 1ml=1cm3 and 1cm=0.01m=10-2m then 1cm3 = 10-6m3 this means that 1lt=1000ml=1000cm3 = 1000 x 10-6m3= 10-3m3 So 1lt/1m2 from the above is 10-3m3/1m2= 10-3m = 1mm. I hope that it is not complicated.
How long does it take peat to form?

How do you prepare 1 mM dpph radical solution?
for prepare 1mM DPPH radical solution: DPPH Molecular weight: C18H12N5O6 = 394g DPPH 1mM = 394/1000= 0.394g/L
How do you prepare 1mM EDTA from 0.1M EDTA?
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.
How do you prepare 1mM edta from 0.1M edta-Na2 solution?
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.
How can we Prepare 1mM NaOH?
0,4 g NaOH + 1000 ml H2O
How do you prepare0.1m dpph solUTION?
1mM DPPH (MW 394.32) solution would be 0.39 mg/1mL 1M = 390 mg/1mL
