Homework Help: Chemistry

Posted by Angeline on Monday, April 20, 2009 at 5:35pm.

A few questions...how many grams are in 48.7x10^24? I don't know how to convert atoms to grams. I can do moles to grams or moles to atoms, but not atoms to grams. My other problem is how do you convert moles to moles as in "how many moles of Cu2O are needed to produce 2.3 moles of Oxygen gas?" The answer is two according to my friend, but I want to know how they reached this. Thanks for your help.
