How many moles of PCl5 in 3.98x10^30 molecules of PCl5? Please show work.

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess

Sorry i dont understand the question can you rephase it?

Your awser would be a acetone

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
