A solution of glucose in water is labelled as10percentw/w, what would be the molality and mole fraction of each component in the solution? If the density of the solution is1.2gmL−1, then what shall be the molarity of the solution?
To find out which solution has the highest mass by mass percentage, we will calculate the mass percentage for each solution using the formula:
Since the extraction of analyte depends on the solvent composition, method development is often done by changing the percent composition of aqueous or switching organic components, e.g.,acetonitrileinstead of methanol. 5. An internal standard (e.g.,leucineenkephalin 250pg/μL) added to DESI solve...
