Homework Help: Chemistry

Posted by Aline on Thursday, April 23, 2009 at 10:47pm.

I am trying to figure out how much 1.134 grams worth of gold will cost, if gold is at 380 dollars an ounce. I set up proportions like this:

380 doll./1.34 grams (how many grams are in an ounce) = BLANK/1.134 grams (mass of coins). I got $321.58. But this is incredibly unrealistic for gold to be $321.58 per gram. What did I do wrong?
