What is the number of moles of chemical units represented by 9.03x10^24? and how do i show work? (dumb it down )

One of the few xenon compounds that form is cesium xenon heptafluoride (csxef7). how many moles of csxef7 can be produced from the reaction of 13.0 mol cesium fluoride with 12.5 mol xenon hexafluoride? csf(s) + xef6(s) csxef7(s)

Summarize possible ways in which phases of matter could combine to form a solution.
