Answer 1

-H= 11.19%

-O= 88.81%

Explanation: the answer above mine is incorrect!, i just did it and i got it right, the answer is h= 11.19% and O= 88.81% hope it helps!

Answer 2

H % = 11.11%

O % = 88.89%

Step-by-step explanation:

atomic weight of H = 1

atomic weight of O = 16

each molecule of water contains 2 atoms of H and one atom of O

hence molecular weight of water = 18

H % = 2 x 100/18 = 11.11%

O % = 16 x 100/18 = 88.89%
