WebNov 4, 2015 · This means that every 100 g of water will contain a total of 11.19 g of hydrogen. Since your sample has a mass of 23.5 g, it follows that it will contain. 23.5g water ⋅ 11.19 g H 100g water = 2.63 g H. Alternatively, you can first find the number of moles of water in get in that 23.5 g sample. 23.5g ⋅ 1 mole H2O 18.0153g = 1.3044 moles H2O. WebWith this convention, the different energy levels of a Hydrogen atom are given by the equation: where E0 = 13.6 eV ( 1 eV = 1.602×10-19 Joules) and n = 1,2,3… and so on so that the ground state has energy E1= -13.6 eV and the second energy level (the first excited state) has energy E2 = -13.6/4 eV = -3.4 eV.
