    I usually don't comment on a lot of videos, but I have watched so many videos relating to chemistry-stoichiometry, and this, by far, is the only video that I was able to understand. I will definitely be watching the MCAT video playlist. Thank you!

    @Max-xh7bx Місяць тому

    18:23 is wrong as it only maintains 2 significant figures out of the three, therefore you must place it in scientific notation as 1.50 times 10 to the 2nd or add a dot at the end to make it 150.

  • @ChristopherMurphy-ug6zf
    @ChristopherMurphy-ug6zf 3 місяці тому

    just want to confirm that there can be more than one answer to problems like the one at 22:50 since some videos on UA-cam will have different molar masses for elements, for example the periodic table my professor gives us to refer to on exams has Hydrogens atomic mass being 1.01, and when I did the problem my total answer was 22.8g H2O not 22.7 since my Molar Mass for H2O is 18.02g ( 2(1.01)+16.00 = 18.02).

    • @MedicosisPerfectionalis
      @MedicosisPerfectionalis  3 місяці тому

      Yes, the number that you will use to calculate the molar mass will affect the final answer.
