Nicotine (C₁₀H₁₄N₂) is a byproduct of the tobacco industry and is used as an agricultural insecticide. Calculate the percent composition of each element in nicotine.

Question

Quizplus · Accepted Answer

The molecular formula of nicotine is C10H14N2. To calculate the percent composition, first calculate the molar mass: C (12.01 g/mol) * 10 = 120.1 g/mol, H (1.008 g/mol) * 14 = 14.112 g/mol, N (14.01 g/mol) * 2 = 28.02 g/mol. Total molar mass = 162.232 g/mol. Percent composition: C = (120.1/162.232)*100 = 74.0%, H = (14.112/162.232)*100 = 8.70%, N = (28.02/162.232)*100 = 17.3%.
