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 best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
