Dissolving solid reagent in DMSO - (Apr/18/2015 )
I have issued that remain unsolved till today.
I want to make 200 µL of 10 mM 2-Nitrobenzoic aldehyde (2 NBA) which dissolved in dimethylsulfoxide
I know that first I need to make 10 mM NBA then I dissolved this to DMSO.
But how many volume of 2 NBA I need to used? Since NBA present in solid form.
Highly appreciate for your helps.
Mw of 2 NBA 151.12
Mw of DMSO 78.13
Use mass= number of moles x molar mass and number of moles = volume x concentration.
Remember that mM is millimole per litre and molar masses are in grams per mole!!!
