The average atomic mass of oxygen is 15.9994 amu. the atomic masses of its three isotopes are as follows: o-16: 15.995 amu; o-17: 16.999 amu; o-18: 17.999 amu which isotope is most likely to have the greatest abundance in nature?

O-16 isotope is most likely to have the greatest abundance in nature.

Explanation:

Atomic mass of an isotopes of oxygen elements:

Average atomic mass of an oxygen atom = 15.994 amu

Isotope with the value of atomic mass closest to the average atomic mass of the oxygen atom will have the greatest abundance in nature. As it will be found in much more greater extent in nature.

Where as isotope which is least close to the average atomic mass will have less abundance in nature.

O-16 isotope is most likely to have the greatest abundance in nature.

15.995 amu ≈ 15.994 amu

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
