A 5.00 g piece of copper is placed in a solution of silver nitrate (AgNO3) in which there is excess silver nitrate. The product produced in this reaction is copper nitrate, Cu(NO3)2. The mass of the silver produced is 15.2g. What is the percent yield for this reaction?
A student used a volumetric pipet to measure the volume of the vinegar sample. The vinegar sample was titrated with NaOH and the acetic acid concentration was determined to be 4.20 %mass. For the second titration, the student used a graduated cylinder to measure the vinegar sample. The student calculated the concentration to be 4.30% mass. In which experiment should the student be more confident of the concentration of the acetic acid? Why?
