H2O is the formula. Therefore, the answer is two. You will learn more about subscripts in your chemistry class. There are two subscripts in this formula.
H=2 and O=1 The only numbers that are shown when writing the formula is the numbers above 1. Thus, we eliminate the one and just know that it is there.
Why do we have subscripts? They tell us the proportion of each element in a compound. In this case the ratio of H to O is
2/1. If you had a chemical formula H2O2 you would then have a completely different compound than water. It would be called Hydrogen Peroxide. The ratio of H to O is 2/2 or reducing that to a common denominator it is 1/1. But in reality it is 2/2.
C6H12O6 is the formula for a simple sugar. So you see that the formula is important and the element's symbols must be combined with numbers we call subscripts.

undoubtedly there are two hydrogen atoms in one molecule of Water. How ever therer are 2x6.023x10^23 h atoms in a mole of water

I do have self assurance in Creationism, yet no longer interior the well-known way. i've got self assurance that God made guy for the time of the recommendations-set of evolution. God gave us eyes to be certain the info, and minds to evaluate what we see. interior the commencing up, right after the form widespread because of the fact the vast bang, despite if in Einsteinian fashions or M-brane fashions, the actual universe consisted of particularly plenty one variety of remember, sub-atomic debris of the two remember and antimatter. the two one in each of those annihilated maximum each thing, leaving hydrogen in super abundance. The hydrogen coalesced till the 1st stars have been born. whilst the main sequence, this is Hydrogen fusing into Helium, runs out, then the helium starts to fuse into heavier and heavier factors, culminating with iron. 2 milliseconds after a famous individual is switched over into iron, it is going Nova, spreading this is heavy factors during area. The very iron on your crimson blood cells grew to become into born interior the middle of a famous individual. All factors have been formed in this form, which paved the way for a universe that could help existence. So, confident, water is formed from 2 Hydrogen atoms and one Oxygen atom, and without them, existence does no longer be accessible as all of us understand it. God is the spectacular Chemist, the spectacular biologist. i admire technology, yet I ought to concede that God blew the spark of existence into the 1st single-celled creature, which billions of years later led to existence as all of us understand it. wish this helps!

Depends on the molecule. But in nature 99%+ is only two.
Heavy water is when it is H202 and deuterium water is 2H20 but its extremely rare in nature and mostly man made. Tritiated water is 3H20.
All COULD be considered water, but generally water is considered to be H20 for non-physicists. And you would never want to consume 2H20 or 3H20 either, bad things happen at the cellular level.
