Calculate the molar mass of adrenaline (C9H13NO3C9H13NO3), a hormone responsible for regulating heart rate and other functions of the sympathetic nervous system. Express your answer to five significant figures.

Explanation:

Hello!

In this case, since the molar mass of a chemical compound is computed by averaging the atomic mass of each element in the molecule and the amount of atoms; which in this case there are 9 carbon atoms, 13 hydrogen atoms, 1 nitrogen atom and 3 oxygen atoms; thus, we compute the average as shown below:

Now, we plug in the atomic masses to obtain:
