Well, the atomic weight of hydrogen is 1.01 grams, and the atomic weight of oxygen is 16.00 grams. These are values of 1 mol of these atoms.
The overall mass of 1 mol of water is:
[math](1.01×2)+16.00 = 18.02g/mol[/math]
Using Avogadro’s number, we can determine the mass of 1 molecule of water:
[math]18.02/(6.022×10^(23))= 2.992×10^(-23)grams[/math]
2.992×10^-23 grams
The overall mass of 1 mol of water is:
[math](1.01×2)+16.00 = 18.02g/mol[/math]
Using Avogadro’s number, we can determine the mass of 1 molecule of water:
[math]18.02/(6.022×10^(23))= 2.992×10^(-23)grams[/math]
2.992×10^-23 grams
