Problem 121P

Nicotine, a stimulant found in tobacco, has the mass percent composition: C, 74.03%; H, 8.70%; N, 17.27%. The molar mass of nicotine is 162.26 g/mol. Find the molecular formula of nicotine.

Step-by-Step Solution:

Solution 121P

Step 1:

Given :

Mass percent composition of C = 74.03%

Mass percent composition of H = 8.70%

Mass percent composition of N = 17.27%

Molar mass of nicotine= 162.26 g/mol

Molecular formula of nicotine= ?

To find the molecular formula, we need to find the number of atoms.

number of moles (n) = $\frac{mass\ of\ element\ }{Molar\ mass\ of\ element\ }$

To find the mass of element here, we multiply the mass percent composition with the molar mass of nicotine.

Mass of carbon (C) = $\frac{74.03}{100}$ $\times{}$ 162.26 = 120.12 g

Mass of hydrogen(H) = $\frac{8.70}{100}$ $\times{}$ 162.26 = 14.11 g

Mass of nitrogen(N) = $\frac{17.27}{100}$ $\times{}$ 162.26 = 28.022 g
