Imagine that you work at a company that prepares chemical solutions. You are asked to label asolution to sell to different customers. One customer is a hospital, another is a chemistry lab at auniversity, and a third is a physics lab at a university. You added 900 kg of NaCl in a 100-litercontainer and filled it with water to a volume of 100 liters. Assume standard (STP) conditions.Determine the following:Mass percentage of the solution for the customer in the hospitalMolarity for the customer in the chemistry labMolality for the customer of the physics lab2. A researcher is often required to prepare solutions in the lab. Typically, a lab provides a concentratedsolution. This solution must be diluted to the proper concentration. Hydrochloric acid is a commonstock solution that is typically purchased at 37.0% HCl concentration (density = 1.20 g/ml). You mustmake 100 ml of 0.25 M HCl to do a DNA extraction experiment. How much of the 37.0% HClconcentration stock do you need to prepare this solution?3. The Haber–Bosch process for fixation of nitrogen is one of the more important chemical reactionsever invented. Without the invention of this process, which is used to make ammonia for fertilizer, theworld’s population would not be as large as it is today.N2(g) + 3H2(g) 2NH3(g)List three ways in which the yield of ammonia in the reaction above can be improved for a givenamount of H2.Additionally, explain the principle behind each method.Copyright © 2013 by University of Phoenix.
