The compound As2I4 is synthesized by reaction of arsenic metal with arsenic triiodide. If a solid cubic block of arsenic (d 5.72 g/cm3) that is 3.03 cm on edge is allowed to react with 1.03x10^24 molecules of arsenic triiodide, what mass of As2I4 can be prepared? If the percent yield of As2I4 was 72.9%, what mass of As2I4 was actually isolated?
