A concentrated phosphoric acid solution is 85.5% H3PO4 by mass and has a density of 1.69 g/mL at 25°C. What is the molarity of H3PO4? What is the mole fraction of urea, CO(NH2)2, in a solution prepared by dissolving 5.6 g of urea in 30.1 g of methanol, CH3OH? How will an understanding of this concept help you in your healthcare career?

It should give a brief description of the importance of the experiment and procedures. Essentially this is an objective. What was the point of the experiment? It should include any changes to the procedure not included in the lab notebook. Otherwise, students must write “Procedures followed as written in the lab notebook.” It should include any tables and graphs (appropriately labeled) and a one-sentence description […]

Name:Exp # Date: Lab Partner Diels-Alder reaction. Experiments 5&6 1. Abstract and Purpose: (2 point). The Diels-Alder reaction is one of the most used reaction nowadays in organic chemistry, being a reaction in which a diene reacts with a dienophile to form an adduct usually in the form of a sixmembered ring. It is a [4+2] cycloaddition reaction between a conjugated alkene called diene and […]
