You have 315 mL of an aqueous solution that is 0.29 M Na2SO4 and a separate 250 mL aqueous solution that is 0.41 M BaCl2- a). How many moles of each of the four ions are present (do not use the word "moles" in your answer, just the number)? Na+ 5042- Ba2+ ci b). When these two solutions are mixed together, what is the chemical formula of the solid expected to precipitate from the mixture? (Don't forget to put (s)...

In an acid-base titration, the neutralization of 20.00 mL of a solution of KOH (potassium hydroxide) of unknown concentration required the addition of 28.60 mL of 0.1042 M HNO3 (nitric acid). Calculate the molarity of the potassium hydroxide solution. Place your answer in the box. Express your answer using only a number or numbers without text. Report your result in decimal notation and to the proper number of significant figures. All numbers are measured.
