Final answer:
The molar mass of norepinephrine (C₈H₁₁NO₃) is calculated by summing the atomic masses of carbon, hydrogen, nitrogen, and oxygen, resulting in approximately 169.178 g/mol. Norepinephrine is a hormone involved in the body's "fight or flight" response, influencing blood pressure and heart rate.
Step-by-step explanation:
Calculate the Molar Mass of Norepinephrine (C₈H₁₁NO₃)
To calculate the molar mass of norepinephrine, we need to sum the masses of all the atoms in a molecule of norepinephrine based on the molecular formula C₈H₁₁NO₃. Here is the step-by-step calculation:
- Carbon (C): 8 atoms × 12.01 g/mol = 96.08 g/mol
- Hydrogen (H): 11 atoms × 1.008 g/mol = 11.088 g/mol
- Nitrogen (N): 1 atom × 14.01 g/mol = 14.01 g/mol
- Oxygen (O): 3 atoms × 16.00 g/mol = 48.00 g/mol
Adding these together gives us the total molar mass:
Total Molar Mass of Norepinephrine = 96.08 g/mol + 11.088 g/mol + 14.01 g/mol + 48.00 g/mol = 169.178 g/mol
Therefore, the molar mass of norepinephrine is approximately 169.178 g/mol.
Norepinephrine is known for its role in the body's "fight or flight" response, where it functions to increase blood pressure and heart rate, among other physiological effects.
