There are 1.66 \times 10^{22} molecules in 1 gram of nicotine.

<u>Explanation</u>:

Nicotine is an organic compound with the chemical formula of C_{10} H_{14} N_{2}

Given  the mass of nicotine = 4.50 g

Molecular mass of Nicotine = 162.23 g/mol

Moles of a compound = given mass / molar mass of the compound

                                     = \frac{4.50}{162.23}  = 0.0277

The Number of molecules of compound:

Moles \times Avogadro number = 0.0277 \times 6.023 \times 10^{23}

                                             = 1.66 \times 10^{22} molecules.

There are 1.66 \times 10^{22} molecules in 1 gram of nicotine.
