Please please help me prepare for my chem. finale?

1 mol of H2SO4 will contain 1mol of sulfur atoms, remember mol is a number (Avagadros number) the amount you have will be the ratio of that particular atom in that particular compound, for example one mol of H2O will have a hydrogen:oxygen mol ratio of 2:1, you will have twice as many hydrogen atoms as oxygen atoms present in a mol of H2O. as with the sulfur you will have 1 mol of sulfur for every mol of sulfuric acid you have. you would have 4x the amount of mol oxygen and twice the amount of hydrogen; H:S:O = 2:1:4, your answer is therefore D.
