I want the solution very quickly within 15 minutes A- Express the concentration (given for water solutions) in ppm, molarity, and molality:1.36*10° moles (NaHCO;) per liter . (The atomic weight of Na=23 , C-12,0-16,H-1).B- A stock solution of dye with concentration of 150 ppm. How it can do to get the dyesolution with concentration of 25 ppm in 150 ml.C- State the methods of expressing the composition of solutions, and then prove thatppm=mg/l.

As per the guidelines, I can only answer first question because you have posted multiple questions.…

Answered: A- Express the concentration (given for…
