    Oh... My.... God. You don't understand how much you've just explained how easy this is to me....I struggled for almost two semesters getting 60s in pre-AP Chemistry as a sophomore. I thought i was stupid but no one had explained it like this, my teacher is to side tracked and does this "rail road" track method I was confused on but i learned everything i need to pass with you guys, THANK YOU.

      Jesseca Alba Fantastic news, Jesseca! Congrats! That's very encouraging. :)

      Jesseca Alba But how did we determined that it's in 12 gm of carbon and 24 gm of magnesium that will have the same number of atoms this could have been 24 gm carbon and 48 gram magnesium that contained same no of atoms. What is the history of determination of atomic and molecular masses.

    Thank you for these lessons. I am 44 and trying to get back to high school with distance learning on my own so having these videos are a big big help. Very Much appreciated Dr.

    After scouting more than 10-15 videos on different sites, yet i could not understand Molar Mass & Mole, however this video has cleared that doubt in the first statement and the table. Thanks Sir I am 46 years old and only understood this after i heard you. I am grateful...........

    Hadn't taken Chem in 3+ years... I am now taking Gen. Chem I in college and my instructor refused to teach how to do conversion again saying we should just remember it and yelling at us when we asked questions about it. Thanks so much for the video. Hopefully with the use of these videos I can pass this class.

    Take 713 grams and divide it by 342.17 g/mol. 342.17 being on the bottom of the conversion means you must divide by that number.

    I don't really understand why the atomic mass of an atom is equal to its molar mass?

  • @osamaasem6119
    @osamaasem6119 10 років тому

    My periodic table is different
    like i have the oxygen 16 and the Fe is 56
    will it make a difference in the exam

    • @GetChemistryHelp
      @GetChemistryHelp  10 років тому

      Sounds like you have a periodic table with limited significant figures. You'll get roughly the same answer, but your significant figures (precision) will be slightly off.

    • @Ahmad-Savage
      @Ahmad-Savage 5 років тому

      In ur periodic table the masses are explained after the round off of no.
      Fe, ( A-55.5) will become Fe( A-56)

      If you want to find the mass in grams it's grams on top and to find moles mass you put MOLES on the top

    • @megatrong1194
      @megatrong1194 10 років тому

      Use conversion factors. E.g 1 mole= __ g

    Hydrogen's Atomic Mass id 1.008. Save rounding oil the end. It gives you an answer that is more accurate!!!!
