it has to be prepared using methanol or ethanol at the concentration we required.
for prepare 1mM DPPH radical solution: DPPH Molecular weight: C18H12N5O6 = 394g DPPH 1mM = 394/1000= 0.394g/L
1mM DPPH (MW 394.32) solution would be 0.39 mg/1mL 1M = 390 mg/1mL
how to prepare .05M glutaraldhyde solution molecular weight is 100.12
A solution of ammonia can be used to prepare ammoniumsulfate by reacting it with a solution of sulfuric acid to produce a solution of ammonium sulfate, which can be dried if desired to prepare solid ammonium sulfate.

for prepare 1mM DPPH radical solution: DPPH Molecular weight: C18H12N5O6 = 394g DPPH 1mM = 394/1000= 0.394g/L
I really dont know people
Dissolve 0,788 g DPPH in 1L ethanol.
1mM DPPH (MW 394.32) solution would be 0.39 mg/1mL 1M = 390 mg/1mL
you should not store DPPH for longer than a day as it degrades rapidly. But I would guess that a glass bottle should suffice

Image result for You prepare a less concentrated H C l solution from a stock solution with 12m concentration. If you too 100g of the stock solution to prepare 4 MHCl solution how much water is needed to prepare o find solution 9density HCL(12) = 1,89/ml? The concentration would be 0.76 mol/L.
How to prepare 0,28% ammonia
A base solution releases OH- and the positive radical of the base.
cresol is prepared with soap solution as it is more soluble in the soap solution than water . moreover soap solution enhances its detergent and disinfectant properties.
