Answer:
C10H14N2
Explanation:
I don't believe one can deduce the molecular formula from just it's molar mass. There are too many possible combinations of elements that could add to the same mass. This is the correct formula for nicotine, taken from known information, not from an analysis of the molar mass alone. One can confirm the molar mass is in the correct range:
C10: 10*12 = 120
H14: 14*1 = 14
N2: 2*14 = <u> 28</u>
Total = 162 which is 160±5g/mol

Answer:
Both atoms achieve a more stable configuration
Explanation:
The mass of a mole of Cu₂O is basically the molar mass of this compound. To find this, add the molar mass of each atom in the compound together. Therefore you will get 62x2 + 16 = 140 grams
