How many hydrogen atoms present in one molecule of ammonium acetate NH4C2H3O2?
To answer this kind of question, all that is required is to add the subscripts that appear immediately after the atomic symbol of the atom in question, remembering that if there is no explicitly written subscript, a subscript of 1 is implied. In this instance, the symbol for hydrogen occurs twice, once with a subscript of 4 and once with a subscript of 3. Therefore, there are 4+3 or 7 hydrogen atoms in the formula unit.
