Question

`nicotine (c10h14n2), a member of the nightshade family of plants, is an oily liquid that makes up between 0.6 to 3% of a cigarette's mass. 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 1.00 g of nicotine?

Answer 1

Answer: There are
`3.67* 10^(21)` number of nicotine molecules in 1 gram of nicotine.

Step-by-step explanation:

NIcotine is an organic compound with chemical formula of
`C_(10)H_(14)N_2`

Given mass of nicotine = 1.00 g

Molecular mass of Nicotine = 162.23 g/mol

`\text{moles of compound}=\frac{\text{given mass of compound}}{\text{molar mass of compound}}=(1.00 g)/(162.23 g/mol)=0.0061 mol`

Number of molecules of compound:

`\text{moles of compound}* {Avogadro number}=0.0061 mol* 6.022\time 10^(23)=3.67* 10^(21) molecules`

There are
`3.67* 10^(21) molecules` in 1 gram of nicotine.
