Now let's calculate the weight percent O in the water in this glass.
Atomic Mass: H = 1.0 amu
O = 16.0 amu

Now let's calculate the weight percent O in the water in this glass. Atomic Mass: H = 1.0 amu |
|
Since 1 mole of water contains 16.0 grams O and the gram-molecular weight of water is 18 grams the weight % oxygen is:
|
Weight %
O =
|
16.0 grams
18.0 grams |
x100 = 88.9% |
