Evaluation of the Gas Law Constant Abstract: The result of the change in volume was approximately 22 CC or 0.00084 mol. This translates into the average for the R constant being 83.8L*atm/K*mol. The four determinations ensured that the results were accurate because more than one trial helps somewhat prevent error. Approximately 0.20g of the Mg ribbon was used for these determinations. Introduction: 1. Theory If the temperature of a gas sample was held constant‚ its volume varied inversely

Abstract Rhesus typing is an important clinical technique which involves finding out whether some ones blood is RhD+ve or RhD-ve‚ it is important to find this out as it can have serious health complications if blood that is un compatible is mixed‚ either during pregnancy or transfusions. This experiment involved using the techniques of PCR to amplify the DNA collected‚ using electrophoresis to separate the DNA and using markers and positive controls of known size to determine the size of fragments
