    I can add for you an short cut. I their was an 3 element, find 2 and minus the 2 element by 100. example: if the element 1 is 50 and the element 2 is 30. 100-50-30 so the third element will be 20%. These is an easy way by wasting non-wastable time in the exam. Regards, Ali from UAE.

  • @tortul1462
    @tortul1462 Год назад +1

    I have a formula for those who have hard time understanding the last part:
    Molar Mass of Molecule =
    (MM of Atom) x (No. of atoms)
    _______________________________
    (Mass % of atom) ÷ (100%)
    ***
    In the example given in the video this'll be it:
    MM of molecule =
    (MM of Atom) x (No. of atoms)
    _______________________________
    (Mass % of atom) ÷ (100%)
    =
    (14.01) x (1)
    __________________
    (13.32%) ÷ (100%)
    =
    14.01
    ______
    0.1332
    = 105.18
    ***
    Additionally, to prove that it is actually the MM of the molecule, you divide the MM of the atom (which is the Nitrogent) divided by the MM of the molecule multiplied by 100%:
    Mass% of N = (14.01 ÷ 105) x 100%
    =
    13.32%
