A chemist has samples of 2 compounds(ClXa and ClXb), each contain Cl and the element X. She then determines that the ratio of mass X to mass CL. = 0.5359 for the ClXa and 1.6077 for the Clxb sample. Identify the mystery element "X".
I see that my it should be ClX1 and ClX3 just from simple division, but how do I figure waht element X is?
