2.98 x 10-18 ugThe mass of myoglobin is roughly 17,000 daltons. There is some variation between species as there are some regions of the globin that are highly conserved (such as in the heme binding pocket of the protein) and some regions that are more variable. Mammalian myoglobin is typically considered to be composed of 153 amino acids.
Oxygen - Atomic Mass: 15.9994.
As the name would suggest, the mass of Oxygen-18 is 18.
Cocaine is C17H21NO4 and has a molar mass of 303.353 g/mole. Mass of oxygen in cocaine is 4x16 = 64. So, % oxygen by mass is 64/303.353 (x100) = 21% (to 2 sig. figs)
Oxygen is a non metal element. Atomic mass of it is 16.
