You have a 1 mg of fluorochrome X with a molecular weight 515.0g that can be dissolved in DMSO at a concentration up to 5 mM. You want to stain your cells at a final concentration 5 uM at a staining volume 100 ul. Q: Outline just how exactly you will dissolve the powder (volumes) to make stocks, what diluent, aliquots, what you will do with left overs (how to store and/or dispose them) and what volumes you will add...
You have an electrolyte, M3N, of which molecular weight is 600 g/mole. The compound is an electrolyte and dissociates as follows M3N = 3M++ N-3 What is the valency of the compound?
