Contact with the liquid pure form can cause death within hours, as nicotine passes through the dermis and heads directly for the bloodstream. Overdoses and death can easily occur in those smoking cigarettes with nicotine patches applied on their body. How many nicotine molecules are in 4.50 g of nicotine?

There are 1.66 1 molecules in 1 gram of nicotine.

Explanation:

Nicotine is an organic compound with the chemical formula of

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

                                     =

The Number of molecules of compound:

Moles Avogadro number = 0.0277 6.023 1

                                             = 1.66 1 molecules.

There are 1.66 1 molecules in 1 gram of nicotine.
