achievement‚ normality is culturally defined‚ and normality is often associated by the term “good”. To argue that modern civilization in not necessarily a human achievement‚ Benedict explains variants of different isolated societies that she has researched they have their own terms of what makes something “good” because they don’t have the influence of what we call a “modern” civilization. Benedict argues psychic ability‚ homosexuality‚ and murder as main points describing that normality is culturally

water in it * wait to dissolve then makeup it to 1l standard flask. iii)Titration for normality of NaOH * take 20ml of NaOH solution in 100ml conical flask add 1 drop of phenolphthalein * the colour changes to pink colour * take oxalic acid in 50ml burette and titrate against NaOH solution .The end point is the appearance of pale permanent pink colour. Formula for normality Normality of NaOH=(burette reading*strength of oxalic acid)/20ml of NaOH Strength of oxalic acid=amount

volume of sol’n Molarity (M) of the solution is defined as the number of moles of solute present in a liter of the solution. Molarity = mol of solute L of sol’n The Normality (N) of the solution is defined as the number of equivalent weights of the solute in 1 L of solution. Normality = equivalent of solute L sol’n The molality (m) of solute is the number of moles solute per 1000g solvent or 1kg solvent. Molality = mol of solute Kg solvent

portion of this experiment was the standardization of 0.1 N KMnO4 solution. In determining the Normality of KMnO4 (FW=158grams/mol)‚ Na2Cr2O4 was used as the primary standard. Na2Cr2O4 was titrated with KMnO4 in three trials. The Normality of KMnO4 computed using the volume of KMnO4 obtained during the three trials on the titration with Na2Cr2O4. The mass of Na2Cr2O4 used (see appendix). The Normality obtained in each trial are slightly close with each other. This may be due to the differences of

Some data points also cross the permissible range‚ but the density of data (high in the middle‚ and low at the ends ) allows for the usage of normal distribution

research Do women’s ideas of ‘normal’ birth match those held by professionals? Abstract Aim: To explore the definitions of normal birth held by women who have not given birth‚ what influences that perspective‚ and compare it with those of health professionals. Background: Available evidence provides conflicting definitions of normal childbirth. The majority of available evidence encapsulates the views of the health professionals themselves or women who have experienced childbirth. Little evidence
