Solved: You have two distinct gaseous compounds made from

Chapter , Problem 90

(choose chapter or problem)

You have two distinct gaseous compounds made from element X and element Y. The mass percents are as follows: Compound I: 30.43% X, 69.57% Y Compound II: 63.64% X, 36.36% Y In their natural standard states, element X and element Y exist as gases. (Monatomic? Diatomic? Triatomic? That is for you to determine.) When you react gas X with gas Y to make the products, you get the following data (all at standard pressure and temperature): 1 volume gas X _ 2 volumes gas Y! 2 volumes compound I 2 volumes gas X _ 1 volume gas Y! 2 volumes compound II Assume the simplest possible formulas for reactants and products in the chemical equations above. Then, determine the relative atomic masses of element X and element Y.
