$$2.81x10^{24}atoms(\frac{1 mole }{6.022x10^{23}atoms})=?$$

I like to read the question and work backwards from the answer to figure out how to solve these. this is a one step problem but it really comes in handy when you are doing larger ones. I would solve this but i don't have my calculator with me and using the computers is not that easy for me.
