I still need help with this question because that answer is not what the question is asking for!
1 g glutamine contain 0,328 g oxygen.
because its impossible for an atom to have a mass
The atomic ratio is 2:1 The mass ratio is 1:8 because oxygen has an atomic mass 16 times greater than hydrogen
Isotopic mas of hydrogen ia '1' Isotopic mass of nitrogen is '14' Isotopic mass of oxygen is '16' It follows that oxygen is the n=heaviest of these gases.
The molecular mass of CO is 28. The carbon percentage by mass is ~43%. Hence the oxygen percentage by mass is ~57%.
32 as oxygen is diatomic

moles = mass/molar mass The molar mass of an oxygen atom = 16 g mol-1, as there are two oxygen atoms in diatomic oxygen this has to be doubled. 42g / 32g mol-1 = 1.3125 moles
all atoms have different masses Mass of an atom is due to protons and neutrons present in an atom and number of proton is something that distinguish between atoms, therefore mass of hydrogen is different to the mass number of oxygen, hydrogen's mass is 1 as it has only 1 proton and no neutrons, and oxygen mass's is 16 as it has 8 protons and 8 neutrons.

RMM is Relative Molecular Mass. e.g. water: 1 mole of water = 18g It is the mass of all the atoms in the molecule added up. The mass of hydrogen is 1 and oxygen is 16 Water is H20 so there are 2 hydrogens and 1 oxygen, this gves a mass of 18. The mass can be found on the periodic table.

The unit for atomic mass is 1/12 from the mass of the isotope 12C.
Molar mass of it is 32gmol-1. It is twice than an atom.
The atomic ratio is 2:1 The mass ratio is 1:8 because oxygen has an atomic mass 16 times greater than hydrogen
1 table spoon = 15 g
Isotopic mas of hydrogen ia '1' Isotopic mass of nitrogen is '14' Isotopic mass of oxygen is '16' It follows that oxygen is the n=heaviest of these gases.
