O=16
H=1
16+1*2=18

H2O = (2 x 1) + 16
= 18

hydrogen has 1...in water u have 2 H so H=2*1=2
oxygen has 16 in water u have 1 O so O=1*16=16
so the H2O=2+16=18

Yes, you would add it in. The compound you have is called a hydrate, which is when one or more water molecules bond to another molecule. Since the water molecules are bonded to the molecule, you include them in the molecular weight.

molecular wt = sum of the atomic masses
since there are 2 Hydrogens in water, you would double its atomic mass (look on a periodic table) and add it to the atomic mass of oxygen (look on the same periodic table)
