The answer is D :) have a nice day!
Solution hopes you will get it.If 1 AMU is equal to 1.6605x10^-24, divide 1 gram by the AMU to find how many atoms in 1 gram.
1 / (1.6605x10^-24) = 6.022282445 x 10^23 You can probably round to four decimal places, so you have 6.0222x10^23 atoms of copper in a gram.
Multiply that by 2.15, the number of grams in a penny (6.0222x10^23) x 2.15 = roughly 1.2948 x 10^24 atoms
