Consider the following data for three binary compounds of hydrogen and nitrogen: %H (by Mass) %N (by Mass) I 17.75 82.25 II 12.58 87.42 III | 2.34 97.66 When 1.00 L of each gaseous compound is decomposed to its elements, the following volumes of H,(g) and N2(g) are obtained: H2(L) N2(L) 1.50 0.50 II 2.00 1.00 III 0.50 1.50 Use these data to determine the molecular formulas of compounds I, II, and III and to determine the relative values for the atomic masses of hydrogen and nitrogen.
