How many atoms of nitrogen are in 3Cu(NO₃)₂?
gpt
There are 6 nitrogen atoms in 3Cu(NO₃)₂.
Explanation: This calculation involves multiplying the number of moles by Avogadro's number and then counting the number of nitrogen atoms in the molecular formula of the compound. Since each molecule of Cu(NO₃)₂ contains 3 nitrogen atoms, and there are 3 molecules in 3Cu(NO₃)₂, the total number of nitrogen atoms is 3 x 3 = 9, and then multiplied by 2 due to the 2 Cu(NO3)₂ units; the end result is that 6 nitrogen atoms would not be the result.  The end result of solving the equation for the particular question is: 9 nitrogen atoms in 3Cu(NO₃)₂.
