Best ResponseYou've already chosen the best response.2Don forget the stoichiometric ratios. for every mole of phosphoric acid, you need 3 moles of NaOH to neutralize it. So you have to include that factor of 3 in the above calculation. It is a 1: 3 not 1:1 relationship. Try it and see.

Best ResponseYou've already chosen the best response.0as i see it you got all you need you just need to put numbers in.... only way to learn how to solve this kind of things is to do it yourself...

Best ResponseYou've already chosen the best response.0this is really basic chemistry, begin with writing equation, then write down what you have and what you need and do the magic... put the relationships of reactants and products in equations and just crunch the numbers...

Best ResponseYou've already chosen the best response.0ok now lets see you have written N(NaOH)=0,005N > that doesnt exist cause N(NaOH) is marking of number of NaOH atoms and it has no units, and furthermore write it one under another not one next to other cause that is vast. now lets see corection...
