Posted by mysterychicken on Saturday, October 23, 2010 at 9:57am.

I still don't understand how to do this problem; grams/molar mass I understand, but I need to see the steps CLEARLY.

43. How many moles are in 25.0 grams of potassium? Show your work and round your answer to the appropriate number of significant figures.

Please, please help with this!
Thanks
