Hi there,

I'm learing Dimesional Analysis in Chemistry right now, and this seems to be confusing, as far as solving for 2 step equations. This is the equation: How many atoms are in 3.6 grams of Copper?

My results so far: Known               Math
                        3.6 g Cu             3.6 g Cu * 63.546 atoms Cu  (divided by)
                                                              1 g CU
                        ? atoms Cu                                           
                                                 Solved by  multiplying (3.6*1)(/63.546)=.056 g Cu
                        63.546 atoms Cu

I know that I still have more steps to go, but I'm confused on how to solve this Dimensional Analysis problem.

Thanks!

63.546 atoms Cu

63.546 is a molar mass of copper, and as such has units g/mol, no atoms here.
