Title: Chemistry Bleach Titration Calculations Post by: Sektor404 on Apr 19, 2013 Data supplied:
[Na2S2O3] = 0.1271 M Average titre = 22.7 mls Pipette voume = 3 mls Using your titration results, calculate the concentration of NaOCl, 'available Cl2' and the cost of that chlorine. [NaOCl] = 0.481 M; [Cl2] = 3.41 %w/v (How do you work these out?? This is what the answer gives me...) 85.2g of Cl2 costs 250 cents (according to my calculations). How much (in cents) would it cost per gram of Cl2? The answer says 2.93 cents/g Cl2 but I cannot figure out how they got this answer! Any help or explanations would be truly appreciated!!!! Thank you Title: Re: Chemistry Bleach Titration Calculations Post by: valesob on Apr 19, 2013 try using wolframalpha it works great

I just visited that website but it didn't help me. I need somebody to go through the process and explain to me how those answers came about? I have supplied all the data I myself was supplied with...I'm just so confused and I really want to know how to solve this question! |
