Water is made of 2 hydrogen and 1 oxygen atoms. The molecular weight for water should be 1+ 1+ 16= 18. Then the amount of water molecule in 11.4 gram of water should be: 11.4g/18= 0.63 moles.
Since 1 water means 2 hydrogen atoms, then the amount of hydrogen atom should be: 2/1 * 0.63= 1.26 moles of hydrogen
