The percentage of hydrogen in water is______.a)1.11%b)11.11%c)8.89 %d)...
There is also one mole of oxygen atoms weighing 16.00 grams in the mole of water and that of hydrogen is 2.00 gram.
To get the percentage of hydrogen, divide the 2 by 18 and multiply by 100.
i.e. Percentage of hydrogen = (2/18) x 100 = 11.11%

Percentage of Hydrogen in Water
Water is composed of two elements: hydrogen and oxygen. The molecular formula for water is H2O, indicating that each water molecule contains two hydrogen atoms and one oxygen atom.
To calculate the percentage of hydrogen in water, we need to determine the ratio of hydrogen atoms to the total number of atoms in a water molecule (hydrogen and oxygen combined).
Step 1: Finding the total number of atoms
A water molecule (H2O) consists of two hydrogen atoms and one oxygen atom. Therefore, the total number of atoms in a water molecule is 3.
Step 2: Finding the number of hydrogen atoms
Since each water molecule contains two hydrogen atoms, the number of hydrogen atoms in a water molecule is 2.
Step 3: Calculating the percentage of hydrogen
To calculate the percentage of hydrogen, we divide the number of hydrogen atoms by the total number of atoms and multiply by 100.
Percentage of hydrogen = (Number of hydrogen atoms / Total number of atoms) * 100
Percentage of hydrogen = (2 / 3) * 100
Percentage of hydrogen ≈ 66.67%
