A compound is found to contain 5 moles of Carbon (C) and 5 moles of Hydrogen (H). What is the empirical formula of this compound? (help pls)

A mixture can be separated.  Everything in a mixture keeps it's own properties and are not chemically joined together.  I am not completely sure about the compound.  Although with the cake example, the ingredients have been mixed and kind of "fused" together upon baking. Hope this helps a little. (P.S. trail mix is a good example of a mixture.)
