1. If the same flask is used for more than one density determination, is it necessary to weigh the empty flask before each determination? Explain why? 2. How will each of the following errors influence the results of your density determination. In other will each error stated below affect your results; will your results be Too High, Too Low, or Unaffected? Explain your answer (a) When determining the density of the solution, you fail to rinse the pipete with the unknown solution after rinsing it with deionized water. (b) Blowing the last bit of liquid from the pipet when the liquid is transferred into the container for weighing. (c) Having water inside the erlenmeyer flask, in which the liquid is to be weighed, before you weigh the empty erlenmeyer flask with the stopper on. 3. If concentrated sulfuric acid (H2SO4) is 98%(m/m) and its density is 1.84g/mL, what is the molarity (M) of the concentrated H2SO4 solution
