H2O.
2
The atomic mass of H2O is 18.01528amu. Each hydrogen atom has a mass of 1.00794amu and the oxygen atom has a mass of 15.9994amu. There is not atomic number for H2O, as it is a compound, not an element. H: 2 x 1.00794amu = 2.01588amu O: 1 x 15.9994amu = 15.9994amu Total = 18.01528amu
yes the number of moles is the the number before the substance for example if the equation is balanced and you want to find H2O and it appears like 3H2O in the equation then their are 3 moles of H2O

A girl who play Kim, Cleos little sister her name is Cleo Massey
301.8g H2O
H2O The little 2 is a subscript that tells you that there are 2 Hydrogen atoms in the compound. There is no 1 after the Oxygen because if there is no subscript, there is an understood 1 atom in the compound.
There is no carbon in H2O (water) molecule
the little numbers are called exponents. Do you mean this? 32. this is an exponent. (the little 2)
Let me help you a little: water is H2O
Are you talking about the number below the symbol? If so, that's the atomic mass number.
The 2 is called a Subscript.
H2O.
H2o is used to give you energy its sort of like water in fact it is water which is why you have drinks called h2o and stuff like that
SO3 + H2O --> H2SO4 commonly called sulfuric acid.
In science, another name for water is H2O. It can also be called dihydrogen monoxide.
