How many grams of Ni(OH)2Ni(OH)2 are produced from the reaction of 27.0 mLmL of a 1.95  M NaOH M NaOH solution and excess NiCl2NiCl2?

Walter White requires a sulfuric acid (Strong acid) solution to use in a very important synthetic reaction.  He finds a bottle labeled H2SO4, but by some strange turn of events, he cannot remember the concentration.  He decides to perform a titration to determine the concentration of the H2SO4.  He pours 22.20 mL of his unknown sulfuric acid solution into a flask and finds that it requires 29.50 mL of 0.57 M KOH (strong base) to reach the endpoint.  What is the concentration of Walter White's sulfuric acid solution? (Enter your numeric answer only, do not use scientific notation, enter 2 decimal places with your answer) For reference: KOH = 56.106g/mol H2SO4= 98.079g/mol Avagadro's number 6.022x1023

How many mL of 0.815 M KI solution are required to react with 50.0 mL of .259 M Pb(NO3)2 solution to form lead(II) iodide?

A 185.0 mL sample of 1.200 M Pb(NO₃)₂ is mixed with 52.50 mL of 1.500 M NaCl, and the PbCl₂ precipitate is filtered from the solution. Then 200.0 mL of 3.000 M NaBr is added to the remaining solution, and the PbBr₂ precipitate is also collected and dried. What is the mass (in grams) of the PbBr₂ precipitate, assuming the yield in each precipitation step is 100%?

What volume of water is needed to prepare 500 mL of a 0.25 M Ca(NO3)2 solution from a stock solution of 5.0 M Ca(NO3)2?

determine the mass of CuS formed when 100.mL of 0.100M H2S and 50.0ml of 0.150M Cu(C2H3O2)2 are reacted. What is the concentration of C2H3O2 in the resulting solution?

What volume of 0.100 M Na3PO4 is required to precipitate all the lead(II) ions from 350.0 mL of 0.250 M Pb(NO3)2  ?

5.00 mL of acetic acid required 37.28 mL of 0.0999 M NaOH to be neutralized in a titration. Calculate the molarity of vinegar.

It takes 28.61 mL of 0.216 M sodium hydroxide solution to titrate 10.00mL of sulfuric acid solution. What is the molarity of the sulfuric acid?
