Use the following information to answer questions 20-24: As a MLT, you are responsible for making Lysis Buffer. You need to make 1.0 L of the Lysis Buffer. The Standard Operating Procedure (SOP) in your lab states the Lysis Buffer has the final concentration of the following: 0.15M Ammonium Chloride (NH4CI) 1g of Potassium bicarbonate (KHCO3) into 1.0L solution 0.0001M Disodium EDTA (MW = 372.24 g/mol) #### TRE ARE TH The GWM of KHCO3 is 100.12 g/mol. Your scale is precise to the one hundredths digit. Per protocol, you measured out 1.00 gram of potassium bicarbonate (KHCO3) and mixed it in 1.0 L of the solution. What is the final concentration (in molarity, aka M) of potassium bicarbonate in this Lysis Buffer? (Enter numerical value only; no units.)
