- You are doing a bacterial transformation in Professor Carrico’s Genetics lab. As you are getting ready, you realize that you are out of a critical solution, Calcium Chloride. You look at the bottle and find the Molecular Weight CaCl2 is listed as 110.98g/mol. You need 10 ml of a 2 molar solution. Briefly describe how you would proceed to make this solution.

Solution Stoichiometry: We need to make a 0.250 M sodium carbonate solution. We will use a 100.00 mL volumetric flask. How many grams of solid sodium carbonate should we add to the flask to make the solution? Use 105.99 as the molar mass, report correct sig figs, and use g as the unit. Solution Stoichiometry: We need to make a 0.200 M calcium chloride solution. We will use a 100.00...

The principal investigator (PI) for the laboratory you are doing research in has tasked with you with preparing 250 mL of an aqueous zinc sulfate (ZnSO4) solution with a concentration of approximately 50. mM- it is not critical for the solution to be exactly 50 mM, it is just critical to know what it exactly is. Proceed through the following steps to quantify the concentration and uncertainty for the solution you prepare. For this question use the following molar mass...

Experiment 7: Grignard Reaction. Introduction Discovered by French chemist Victor Grignard, the reaction that now bears his name is an example of the preparation of an organometallic reagent. In this lab, phenylmagnesium bromide is the Grignard of interest, and it will be added to an aldehyde to produce an alcohol. Lab Objectives 1. To study organometallic reagents in general. benzophenone. 2. To prepare phenylmagnesium...

Grignard Reaction with a Ketone: Triphenylmethanol Introduction: The purpose of this lab is to prepare phenylmagnesium bromide, a Grignard reagent, and react it with benzophenone to give triphenylmethanol. Grignard reagents are very reactive and must be synthesized in an environment free of water or any other source of potential proton donor. Once made, the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone, benzophenone. The result is an alkoxide that is then protonated to give...
