Calculate the mass of one mole of dopamine, a neurotransmitter with the molecular formula C₈H₁₁NO₂. A) 22.0 g B) 43.0 g C) 82.0 g D) 153 g E) 164 g

Question

Quizplus · Accepted Answer

The molecular formula for dopamine is C8H11NO2. To calculate the molar mass, add the atomic masses of all atoms in the molecule: (12.01 g/mol * 8) + (1.01 g/mol * 11) + (14.01 g/mol * 1) + (16.00 g/mol * 2) = 96.08 g/mol + 11.11 g/mol + 14.01 g/mol + 32.00 g/mol = 153.2 g/mol, which rounds to 153 g/mol.
