how many grams of each species will be present at the end when 0.500g of copper is added to 2.500g of AgNO3? Cu(s) + 2 AgNO3(aq) --> 2 Ag(s) + Cu(NO3)2 (aq)

1. A single mole of AgNo3 weighs 169.88 grams. In order to make a 1M solution, how many grams of AgNo3 would need to be dissolved in 5oomL? How many moles do you need? moles = M x L. please help today

0.550g sample containing only nacl and kbr.it dissolved in water and titrated with a 0.0322M solution of agno3. complete titration of both halides was found to require 30.45ml of agno3 solution. calculate the weight percent of cl in the solid sample.

Ag^+(aq) + Cl^-(aq) ==> AgCl(s) You are starting with 1.054 x 0.103 = grams Cl^-. Use stoichiometry to calculate how much Ag^+ is needed, convert that to AgNO3 to know how much AgNO3 is needed. In the preamble the talk is about adding a slight excess, and that is correct, ...

what is the precipitate formed when HCl is added? I believe the answer is NaCl, but I am not sure and this precipitate only formed in the first NaOH extract, as precipitate was essentially nonexistent in the 2nd extract? Below is what was done in the experiment. Also, does the...

We add excess Na2CrO4 solution to 27.0 mL of a solution of silver nitrate (AgNO3) to form insoluble solid Ag2CrO4. When it has been dried and weighed, the mass of Ag2CrO4 is found to be 0.420 grams. What is the molarity of the AgNO3 solution? Answer in units of M

Chemistry
AgNO2 = 108 + 14 +3(16) = 170 g/mol Ag = 108 g/mol so AgNO3 is 108 grams silver/170 grams Agno3 1 gram silver(170 g AgNO3/108 g Ag) = 1.57 grams
