$4\mathrm{.}12$x $10^-4$M of p$-$nitrophenol is the concentration of initial$/$given stocl solution. Prepare a solution of the following concentration:

$36$ micromoles$/$liter$.$ Measure its absorbance at

$400nm.$

How will you prepare $1mL$ of the assigned solution?

Below, enter the volume of pNP stock solution you

will pipette, and the amount of $0\mathrm{.}100M$ sodium

bicarbonate. Answer in microliters.

Answer:

Final Solution:

volume of stock $pNP$ solution

required is $87\mathrm{.}38L.$

volume of $0\mathrm{.}1MNaHC{O}_3$ solution

required is $912\mathrm{.}62L.$
