    Wow after 2 years of college, and a bit of frustration with Chemistry, I find a free site on UA-cam that does a much better job of teaching and laying out the basics. I wish all teachers used this multi dimensional approach that blends so many different learning styles together. I have been stuck trying to teach myself Chemistry. There is something wrong with how our education system works. Thank you for your amazing, clear videos. PS Love the mind-map like concept maps.

    Consider the following :

    A) how many moles of HCL are there in 100 ml of a 1M solution
    B) what mass of LiOH would react with this quantity of HCL ( assume complete reaction and 100 % yield )?
    C) what mass of LiCl would be produced

  • @akaijahr8219

    @5:57, how is oxygen the limiting reactant when it's less than the amount we were given? Isn't limiting reagent is where the product that's greater than what was given. I thought Methane would be the limited because its out of the amount that's give to us, It's 27.4 and we were given only ten grams of it. Can someone explain?

    Hi everyone!
    I'm currently doing Stoichiometry and was given this question:
    A compound consists of C, H and O only. When 10.68mg of this compound undergoes combustion 16.01mg CO2 and 4.37mg H2O are produced. The compounds molar mass is 176.1 g/mol. Determine the molecular formula of the substance.
    I can get part way through it but I was wondering if anyone here could help me out?
    Cheers

  • @lukedives8575
    @lukedives8575 9 років тому +3

    Dammit America! This is such a complicated way of doing it. I find that the equations we use are so much simpler and easier. m=nM where m=mass, n= number of moles and M= molar mass. And when doing gaseous equations, V=(n)(22.4). You can manipulate these equations depending on what they ask you to find by using normal mathematical principles for equations.

    The answer to the question you gave as 40 liters of H2O in response to your video in the 6th-minute 40th second and the answer in the 7th minute and 50th second is wrong! Because in standard conditions STP is also water liquid. and STP does not work for solids and liquids. STP only works for gases.
