POST-LAB QUESTIONS:Using stoichiometry to find the molar mass of your acid1. Use the volume (mL) of KOH used to reach the equivalence points, the exact molarity of KOH, and the volume (mL) of the unknown acid you titrated to calculate molarity of unknown acid. [see page 5]i) If using the 1st equivalence point then mol H2A to mol KOH is 1/1. So: (MV)acid = (MV)baseii) If using the 2nd equivalence point then mol H2A to mol KOH is 1/2. So: (MV)acid = ½ (MV)base

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
