The best answer is D.
The mass number of an element is the sum of the number of protons and the number of neutrons. Protons and neutrons both weigh about one atomic mass unit or amu.
The nucleus of an atom is made up of protons and neutrons. Both these two types of particles are almost the same size. Almost all the mass of an atom (99%) is in the nucleus. Atomic mass therefore is really a measure of the size of the nucleus.
I think the molecules that will easily <span>dissolve in water based on polarity not on size would be as follows:
</span><span>CH and small 3 with H OH
</span><span>CH and small 2 with H OH
These molecules would indicate they are alcohols which are definitely soluble in water. Hope this helps. Have a nice day.</span>
