Help! Lab Report: Sources of Error section, and the teach says we can't use errors of measurment!?

tiny amounts of chemical can stick to differnt things, like stir bar, stir rod, thermometer and if you remove these items before the experiment is over then you remove some chemicals.  Other kinetics events that your not considering. as in pressure, humididtym and so on.  If you used a Ph probe then maybe it wasn't calibrated right or isn't properly maintained

You got it backwards - inches and feet, and quarts and gallons and etc, etc, are practically ancient units that someday, I hope, the metric system will replace entirely.  I don't know why there is so much resistance to this here in the US, but the attempt has been going on for decades.  I'm sick of having to have 2 sets of every type of wrench and socket, and always having to guess which one goes to some particular fastener on my car, which contains some metric, some SAE.

Use this online converter\nhttp://www.kt.rim.or.jp/~tyamamot/pt.htm\n\nPut in size then choose unit as mm\nConversion standard is American Standards Association 1933\nNumerical format is "real"\nClick "CALC"\nThen scroll down to "results" & look for the result for the 1/72 inch point system\nCross check: 1pt  (1/72inch point system) = .35277777777777775mm....or 1mm = 2.8346456692913384 pt (1/72 inch point system)

Do your own homework. You're a college student. Don't be lazy and tell us to do your work for you. I mean, what if your professor finds out you're getting your ideas from Yahoo Answers and fails you? You're a big girl. DIY.

I worked with 1,000 holders, just to get rid of some of the decimal points.  Out of 1,000 holders, 500 would be made by System A.  Of those 500, 15 will be defective.  System B makes 300, 12 of which will be defective; System C makes 200, 10 of which will be defective.  Out of every 1,000 holders, 37 will be defective and 15 of those 37 defectives will be made by System A.  15 divided by 37 is 40.54%.  I agree with your answer! :D

try the conversion table. europe uses metrics

Ask your instructor to narrow the assignment.\n\nOr, make an assumption as to what the instructor wants, and go forward using your assumption.  (I did this once, and because I was the first one done, the instructor accepted my assumption, although it wasn't what he had inmind.)

The sources of error will always depend on the way you carry out the experiment. To measure the heat directly wouldn't work well. So you need to monitor the temperature at both ends. Monitoring the temperature at both ends, the errors will be the scale error of your measuring device, the quality of the thermal contact between the sensor and the fluid as well as the effect that the sensor has on the flow of the fluid (I'd use fibre optic sensors as they are non-invasive and don't have the problems asociated with using electrical test equipment in water).

Dude, it's in the chapter, read it and plug in those numbers.  Textbooks NEVER give difficult problems that you cant just plug in the numbers into an example provided in the text of the chapter and figure the answer out.

contact the company that made the test, they should have sample problems

I think I can help you with this one... I learned how to do it in Kindergarten.\n\nPull your head out of your ass and measure.\n\nGood Luck!

Off the top of my head, don't hate me if there are errors...\n\nclass MyVar\n{\npublic:\n  int a;\n  MyVar ( MyVar& src )\n  { a = src.a; }\n}\n\n...\nMyVar p;\np.a = 5;\nMyVar q(p);\n// q.a==5 is true

If it was given to you fairly, use it as incentive to work harder. Maybe ask your teacher what you can do to improve. If it was given to you unfairly, politely ask the teacher to change it. If he/she will not, file a formal complaint.

Umm...If you're going to ask questions about your lab assignment  here, you should at least make the questions ones that don't need our direct observation of your experiment to answer.\n\nLook at your lab notes (you took notes, right?) and write down in your discussion whether you saw growth on the agar.

Need more info,  what does the error say??
