Nicotine has the chemical formula C₁₀H₁₄N₂. What is the formula mass of nicotine?

Question

Quizplus · Accepted Answer

To calculate the formula mass of nicotine, we need to find the sum of the atomic masses of all the atoms in the chemical formula.

C = 12.01 u
H = 1.008 u
N = 14.01 u
O = 16.00 u
S = 32.07 u

Formula mass of nicotine = (10 x C) + (14 x H) + (1 x N) + (1 x O) + (2 x S)
= (10 x 12.01) + (14 x 1.008) + 14.01 + 16.00 + (2 x 32.07)
= 162 amu

Nicotine Has the Chemical Formula C10H14N2
