A.2. Preparing the sample It is necessary to prepare the samples for the analyses. The samples are digested using a microwave method. After digestion, the samples are diluted with a 0.10 M nitric acid (HNO3) solution. This HNO3 solution must be prepared. (i) Calculate the volume of the commercial solution needed to prepare 100 mL of a 0.10 M HNO3 solution. [6 marks] The density and concentration of a commercial nitric acid are 1.227g/mL and 37%, respectively. MHNO3 = 63.01 g/mol
