In Day 1 of the kinetics Lab, you will start by mixing a stock solution of Methyl Orange that you will then dilute 5 times in order to have a set of solutions to test the response of your colorimeters. You will calculate the [MO) in your stock solution that you will draw from to make your 5 diluted solutions. To make the stock solution, you add 3.10 mL of deionized water, 3.04 mL of 2.0 M HCl, and 4.07 mL of 139 g/L Methyl Orange into your graduated cylinder. Assuming that the molar mass of MO is 327.33 g/mol, what is the [MO) in this mixture in units of molarity? The solution of Mo that you made above is your stock solution from which you will make the five solutions of Mo that you will run in your colorimeter. For your first dilution you use 0.99 mL of your MO stock solution with 4.99 mL of deionized water. You mix these two liquids in a clean test tube. What is the [MO] in this test tube?

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
