    I love how you talk like you are asking yourself and/or teaching. Instead of talking to us like we should already know this and skip steps. In fact you do the opposite. You teach us as if we are new. I thank you for this and please not stop teaching us like this. Thank you once again.

    The best textbook *by far* is Maitland Jones' Organic Chemistry, which goes step by step and explains the reasoning behind all the reactions, so you're not just memorizing a bunch of stuff that doesn't make sense. I haven't found many great online resources. Khan Academy isn't very good for Orgo (in my opinion) but, you know, it's there and watching it can't hurt.

    The order doesn't matter, because they're all multiplied together. n*R*T = n*T*R, just like 2*4*3 = 2*3*4. When you have a question like this next time, try it yourself in the calculator and see if you can figure out if it affects the outcome on your own. I'm happy to answer these questions, but there's a lot you can learn by yourself.

I watch your videos after every class of chemistry, my teacher is very bored to explain the steps most of the time, and we are always left with question marks after. But I'm happy to come home and watch your videos going through the steps and to be able to understand it better since you make chemistry seem so easy :)))) Thank you !!!!!!!

    What if you are given liters 24 liters of N2, 75 degrees C and 2.30atm, and we're asked to solve for grams of NaN3, instead? Would you plug liters in as V, into PV=nRT and solve for moles (n)? The do a mole:mole conversion between N2 and NaN3....then convert moles of NaN3 to grams?

  • @samanthalopez27
    @samanthalopez27 12 лет назад

    When you were doing the ideal gas law, it was v=nRT/P, but when you plugged in the givens, you changed the order to v=nTR/P. Does the order matter? Will it change the outcome with your calculator? Thank you. :)

    Suppose the teacher tells you length never changes but sometines he says the length is 36.0, other times he says it is 3.0 and sometimes 1.00.
    Are they the same? Yes, because 36 inchs = 3 feet = 1.00 yard.

    I think it would make more sense to round based on the data given in the question. Since 75 degrees Celsius was measured to 2 s.f., how can your answer be more accurate than that? Regardless of converting to kelvin. You're converting a less accurate measured number to a more accurate number.

    • @cullenhutchison6528
      @cullenhutchison6528 8 лет назад

      Imagine: There is a mercury-based thermometer that measures up to the equivalent of 1 kilo-Kelvin (1000 Kelvin) with marks every 0.010 kilo-Kelvin (impractical, yes--but bear with me). One finds a temperature reading of 0.348 kilo-Kelvin, and thus it has 3 significant figures. For the purposes of modern society, however, the person converts it to kilo-degrees Celsius, and subtracts 0.273 kilo-Kelvin. The resulting value is 0.075 kilo-degrees Celsius, and since subtraction was used, we still have 3 significant figures, with the 0 after the decimal point holding a significant place, even though it wouldn't under a normally-measured circumstance. Wishing to make the value more understandable to most people, the 0.075 kilo-degrees Celsius is then converted to 75 degrees Celsius--and since this is a simple conversion of the same unit, the same number of significant figures would carry through--so you would have 075 degrees Celsius, all digits significant, but it would be written as 75 degrees Celsius.
      I hope that made sense! It is very confusing, and I'm not used to teaching or explaining, but I tried.

    • @stephanoparaskeva820
      @stephanoparaskeva820 8 лет назад

      Your analogy was terrible hahah, but I think I followed what you're saying a little: It was converted from kelvin to degrees for simplicity, the sigfig didn't change but due to the rules of sigfig we aren't able to keep the 'accuracy' (is that the word here?).
      But another question arises, how do you know this background information from the question. Because with this logic -- can't every data value be treated in the same way even without prior information, how would you ever answer a question if so?
