4) If you add 3 mL of water to 1 mL of pNp and get an absorbance of 0.2, what is the concentration of the original pNp solution?
Added by Malia D.
Step 1
Since we added 3 mL of water to 1 mL of pNp, the total volume is now 4 mL. The dilution factor is the ratio of the final volume to the initial volume: Dilution factor = $\frac{Final\ volume}{Initial\ volume}$ = $\frac{4\ mL}{1\ mL}$ = 4 Show more…

The molar absorbance coefficient for PNP is 18,000 M-1cm-1. If the absorbance of PNP is 0.629 at pH 10 and a wavelength of 400 nm, what is the concentration (in µM) of this sample? Remember the path length is 1 cm and this sample was not diluted.

the absorbance value this sample was 0.362. this sample wasn't diluted so DF=1. if the equation of the standard curves line was y=0.0029x+0.0471 calculate the concentration of PNP in this sample

To determine the concentration of $\mathrm{SO}_{4}^{2-}$ ion in a sample of groundwater, $100.0 \mathrm{mL}$ of the sample is titrated with $0.0250 M \mathrm{Ba}\left(\mathrm{NO}_{3}\right)_{2},$ forming insoluble $\mathrm{BaSO}_{4} .$ If $3.19 \mathrm{mL}$ of the $\mathrm{Ba}\left(\mathrm{NO}_{3}\right)_{2}$ solution is required to reach the end point of the titration, what is the molarity of the $\mathrm{SO}_{4}^{2-} ?$
