Using a Dumas method‚ you are asked to identify the unknown pure liquid by comparing the molar masses of the given possible substances (ethanol‚ methanol‚ isopropanol‚ acetone). Introduction Dumas Method allows us to measure the molar mass of the substance‚ using the Ideal Gas Law. The Ideal Gas Law‚ PV=nRT‚ explains the behaviour of the gases that are near 100kPa and in the room temperature. This equation shows the product of the pressure(P) and volume(V) equals to the product of the number of moles(n)

Question: The scientific method starts when you ask a question about something that you observe: How‚ What‚ When‚ Who‚ Which‚ Why‚ or Where? And‚ in order for the scientific method to answer the question it must be about something that you can measure‚ preferably with a number. Your Question Do Background Research: Rather than starting from scratch in putting together a plan for answering your question‚ you want to be a savvy scientist using library and Internet research to help you find the

One afternoon‚ while finishing up your shift as the stock manager at Circus Supermarket‚ the manager tells you that he desperately needs some help with an inventory problem. In the back of the store‚ he shows you an unmarked‚ unopened tin can and explains that the store’s owners are threatening to fire him and all his staff if they cannot keep track of the items that they sell. He asks you to help him figure out what is inside. There is one catch: He does not want to open the can‚ just in case there

Internet Activity #2 Scientific Method What is the scientific method? Who uses the scientific method and why are we interested in using the scientific method? First off the scientific method is a procedure consisting of systematic observation‚ measurement‚ experiment‚ formulation‚ testing‚ and modification of a hypothesis. Everyone from scientist‚ mathematicians and even you can use the scientific method. We are interested in using the scientific method because we can solve problems or answer scientific

1. Assume the room rate for a 3-star hotel in Paris follows a normal distribution with a mean of 175€ and a standard deviation of 16€. What is the probability that a randomly selected 3-star hotel has a room rate of Z(X) = (x-μ)/σ σ=16 μ=175 a) Less than 195 Euros? Z (195) = (195-175)/16 = 1‚ 25 so 89‚ 4% b) More than 180 Euros? Z (180) = (180-175)/16 = 0‚ 31 so 62‚ 2% c) Exactly 170 Euros? Z (170) = (170-175)/16 = - 0‚ 31 so 37‚ 8% d) Between 150 and 182 Euros?

Mixed Methods as a Means to Overcome Methodological Limitations of Qualitative and Quantitative Research Recent meta-analyses about mixed method studies (cf. Bryman 2005) have shown that qualitative and quantitative methods are often combined in ways which lead to unrelated research results. One reason for this could be the fact that the ongoing discussions surrounding Mixed Methods still fail to address important methodological issues referring to the methodological limitations of both qualitative

Research Methods Experimental research is a type of research that is used in behavioral health. Participants are randomly assigned to one of two (or more) conditions. The fact that participates are randomly chosen gives the researcher a better knowledge of the differences that occur when between the groups after exposure to the conditions and can be inferred to be a result of the effects of the conditions (Straub‚ 2012). The actual description to experimental research is commonly used in sciences

Descriptive Research Methods (Ch. 12) Case Studies: Detailed analysis of a single (or limited number) of people or events. Case studies are usually interesting because of the unusualness of the case (Three Faces of Eve‚ Mind of a Mnemonist) and/or the detail and apparent insightfulness of the conclusions drawn by the writer (e.g.‚ Freud’s cases such as ‘Little Hans’). The major problem with case studies is the problem of objectivity. The person who is presenting the case usually has some theoretical
