    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.

    just want to confirm that there can be more than one answer to problems like the one at 22:50 since some videos on RUclips 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  8 месяцев назад

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