molecular mass of antifreeze in the 20% solution. 7. Average the molar masses you calculated in questions 3 and 6. 8. The formula for antifreeze is C2H6O2. Calculate its molarmass using the periodic table. 9. Calculate your percent error. Conclusion: This lab was a phenomenal success! The purpose of determining the freezing points of water‚ 10% antifreeze‚ and 20% antifreeze was not only accomplished‚ but also done so in a splendid manner. The net figures of our experiment were

When building the bridge I have to focus on the structure‚ details and actually putting it together right. The structure of my frame I made with the thicker wood‚ but it should have been placed different. Looking at the data from testing other bridges‚ the bridges who double bonded their wood at the bottom last a lot longer that the one piece of

This case study is about Circuit Board Fabricators‚ Inc. which manufactures circuit boards for several companies like Apple Computer and Hewlett-Packard to name a few. Circuit Board Fabricators‚ Inc. plant was designed to produce 1000 boards per day but they cannot meet such production levels as their process engineer insists. On a good day‚ Circuit Board Fabricators‚ Inc. is able to produce around 700 boards. One will analyze and see how Circuit Board Fabricators‚ Inc. can meet the 1000 board requirements

MY PERCEPTUAL MAP OF CAR BRANDS Bonita Stuckey Marketing-421 Jan Peterson-Instructor PERCEPTUAL MAP – CAR BRANDS Summary Perceptual mapping is a technique that allows one to visualize the positioning of different brands in the market. Using perceptual maps‚ one can quickly compare different brands and make strategic decisions about whether or not your brand need to be repositioned. I chose to do my Perceptual Map on different Car Brands. The cars I chose are as follows: Audi BMW Mercedes Ford

people‚ but in order to learn from your mistake‚ you must first be willing to admit it. Making mistakes is not necessarily a bad thing. Mistakes happen every day. We are human and we are expected to err. What is important is that you see where the error happened‚ identify how it happened‚ and set up a process so it does not happen again. “Ownership is the ability to connect current circumstances with what I have done” (Conners‚ Smith‚ & Hickman‚ 2004‚ p. 101).

leave much room for error. Any incorrect code in a programme could lead to errors in the machined component‚ for example if a datum point is not set in the right place then only part of the component may be drilled/milled in the wrong place; errors in the finished component will mean the entire written programme will have to be thoroughly checked through again‚ which again is very long and mistakes in the code are not easily identified by the same person who wrote it. If the error is so small the fault
