The current price of pure gold is $45.00 per gram. A jewelry dealer offers to pay Jemma $600 for her solid gold ring which is composed of 3.67x1022 atoms of gold. Is this a good deal (for Jemma)? Show your work to explain your reasoning.
yes it is a good deal.
At. weight of the Gold (Au) is = 196.97 ( 197 g )
Avogadro's number in one mole are = 6.022 X 1023
means 6.022 X 10^23 atoms weigh 197 g.
1g contain of atoms
1g = 0.3057 X 1022 atoms
means 3.67 x 1022 atoms is equal to 12 gms of gold.
and cost of 12 gm gold will be 12 X 45 = 540 $
which is less then $600 therefore it is good deal.
