Best ResponseYou've already chosen the best response.0Next step? Xishem answered something similar earlier in your other question. So now you have to put in the right equation.

Best ResponseYou've already chosen the best response.1That is incorrect. You have to divide the # of atoms in the sample by Avogadro's #.\[\frac {15*10^{23} atoms}{6.02*10^{23} atoms/mol} \approx 2.49 mol\]

Best ResponseYou've already chosen the best response.0Brent, you have to make sure you know how to do these and understand the logic. Many people here can help you by explaining it. But you have to try to understand the concepts!
