Hey guys, I have two stoichiometry questions to do with solvents. Both of them are very simple and I am unable to complete them at the moment because of some silly error in my method, I am sure. Can you please explain the method and how to do the question in some detail? I really appreciate your help. 6) What volume of 0.250M Sulphuric Acid (H2SO4) is needed to react completely with 13.5g of Sodium Hydroxide(NaOH)? According to this equation: 2NaOH(aq) + H2SO4 = Na2SO4(aq) + 2H2O(l) 7) 200mL of 0.105 M silver nitrate is added drop wise to 25mL of sodium chloride until all the chloride precipitates as silver chloride: AgNO3(aq) + NaCl(aq) = AgCl(s) + NaNO3(aq) * What is the concentration of the original sodium chloride solution? * What is the mass of silver chloride precipitated?
