Chemistry: Exercise 1: Part 1: Part 2: Heptane is a solvent. To determine its density d, we pour 50mL of Heptane in a Test tube. We weigh the test tube filling by Heptane in an accurate balance the mass measured is 94.35g. Knowing that the mass of an empty Test tube is 60.35g. 1- Calculate the mass of Heptane existing in the test tube? 2- Calculate the volumetric mass of the Heptane? 3- Deduce the density of the Heptane 1- Give an overview of chromatography technics 2- What are the chemical elements that we can detect them by these indicators: Iodine solution. Anhydrous copper sulphate. Limewater
