A solution of NaCI(aq) is added slowly to a solution of lead nitrate, Pb(NO,),(aq), until no further precipitation occurs. The precipitate is collected by filtration, dried, and weighed. A total of 18.42 g PbCI, (s) is obtained from 200.0 mL of the original solution. Calculate the molarity of the Pb(NO,),(aq) solution. concentration: M

A solution was made by adding water to 0.293 g of H2ZH2Z until the volume totaled 25.00 mL. Subsequent titration required 40.50 mL of 0.093 M sodium hydroxide. Calculate the molar mass of H2ZH2Z (in g/mol).

when 100.0 mL of a 2.00 M solution of KOH(aq) is added to 100.0 mL of a 2.00 M solution of Mg(NO3)2 what is the mass of the precipitate(s) that form?

Solid potassium cyanide is slowly added to 75.0 mL of a 0.360 M nickel(II) acetate solution until the concentration of cyanide ion is 0.0231 M. The mass of nickel ion remaining in solution is  grams

4. A solution of 75 mL NazCO3 is neutralized with 67.2 mL of 0.1065 M HCI. In the another analysis, 50 mL NazCO3 is added to a solution of 25 mL Ba(NO3)2, and after the barium carbonate was precipitated, the excess of NazCO3 is neutralized with 14.8 mL of the same acid. According to this, what is concentration of barium nitrate (261.337 g/mol) in molarity and g/L?
