The formula of water is
. Thus, molar ratio is 2:1.
Thus,
Number of moles are related to mass and molar mass as follows:
Here, m is mass and M is molar mass
Molar mass of hydrogen is 1 g/mol and that of oxygen is 16 g/mol
Converting molar ratio into mass ratio as follows:
Also,![\frac{m_{H\times M_{H}}}{m_{O}\times M_{O}}=\frac{2}{1}](/tpl/images/0167/2918/e68fb.png)
Putting the values of molar mass,
Thus,
Thus, water is always made up of 32 part hydrogen to 1 part oxygen by mass.
