- BSA for concentration measurements is often prepared as a 10 mg/mL stock solution. Suppose you wish to prepare a series of 10 mL solutions of BSA at 1.0, 0.8, 0.6, 0.4, and 0.2 mg/mL. Using the dilution equation C1 × V1 = C2 × V2, you plan to do this by transferring a calculated volume (V1) of the 10 mg/mL (C1) into a clean test tube, then adding water in sufficient volume to produce 10 mL (V2) at the desired concentration (C2). Complete the table below, showing the volume of stock 10 mg/mL solution you need to add to each tube, and the volume of water you need to add to each. Also, convert the desired mg/mL concentration values to their equivalent in μM (micromolar; 10-6 M).You made 100.0 mL of Pb(NO3)2 solution for lab but forgot to cap it. The next day you noticed that there was only 80.0 mL (silly evaporation) of your Pb(NO3)2 solution left. In addition, since you are a normal high school student, you forgot to write down the original Molarity of the Pb(NO3)2 ☹. You are dying to know the answer, so you decide to use your chemistry skills to solve the mystery. You measure out 2.00 mL of the Pb(NO3)2 solution and add an excess of a concentrated sodium chloride solution. You collect 3.407 g of PbCl2 (s). What is the original concentration of the Pb(NO3)2 solution [before your let all that water evaporate].How many ml of concentrated hydrochloric acid (16.0 M) is required to prepare 251 ml of 6.00N hydrochloric acid?
