If a solution of 10 mg/ml methyl orange is diluted 100 times, 1 ml added to 99 ml of water for example, what is the final concentration? A. 1 mg/ml B. 0.1 mg/ml C. 0.001 mg/ml
A blood sample with a known glucose concentration of 102.0 mg/dL is used to test a new at home glucose monitor. The device is used to measure the glucose concentration in the blood sample five times. The measured glucose concentrations are 109.7, 92.4, 101.2, 104.5, and 104.2 mg/dL. Calculate the absolute error and relative error for each measurement made by the glucose monitor. A. 109.7 mg/dL absolute error = mg/dL relative error = B. 92.4 mg/dL absolute error = mg/dL...
12. Given a series of 4 dilutions, each 1/5, what is the concentration in tube No. 3 if the original concentration was 100 mg/dL? 13. A 1/2, fourfold serial dilution was performed. The original concentration of the analyte was 1200 μg/dL. What is the concentration of the analyte in the final tube? 7. Calculate the true analyte value given the following information: Analyte diluted using 10 μL into 90 μL diluent; Diluted analyte value = 85 mg/dL.
ncetoi paper) 1. BSA stock solution A has a concentration of 3.50 mg/mL. 1.00 mL of stock solution A is diluted to a final volume of 5.00 mL to prepare solution B. 1.00 mL of solution B is diluted to a final volume of 5.00 mL to prepare solution C. 1.00 mL of solution C is diluted to a final volume of 10.00 mL to prepare solution D.

2. The concentration C (in mg/dl) of a certain antibiotic in a patients bloodstream is given by C= 50t /t^2+ 25 where t is the time (in hours) after taking the antibiotic. a. What is the concentration 4 hours after taking the antibiotic? b. In order for the antibiotic to be effective, 4 or more mg/dl must be present in the bloodstream. When do you have to take the antibiotic again?
Prepare the buffer. In this lab we store our buffer at a concentration 20 times the concentration used in the experiment. Thus we call it 20xLB. Before we can use it, it needs to be diluted to a 1x concentration. If we needed 20 mL of the media, we would take 1 mL of the 20xLB buffer and diluted it with 19 mL of Dl water. To make enough buffer for this experiment, we need 50 mL for the gel...
