# What is the molar mass of adrenaline (C9H13NO3) ?

Molar mass just means the mass of

So, the molar mass of

In turn,

#9# moles of carbon.#13# moles of hydrogen.#1# mole of nitrogen.#3# moles of oxygen.This tells us that:

#C_9H_13NO_3 = 9xxC + 13xxH + N + 3xxO# Sign up to view the whole answerBy signing up, you agree to our Terms of Service and Privacy Policy

To find the molar mass of adrenaline (C9H13NO3), you sum up the atomic masses of all the atoms present in one molecule of adrenaline.

C: 9 atoms * atomic mass of carbon H: 13 atoms * atomic mass of hydrogen N: 1 atom * atomic mass of nitrogen O: 3 atoms * atomic mass of oxygen

Using the periodic table, the atomic masses are approximately: Carbon (C): 12.01 g/mol Hydrogen (H): 1.008 g/mol Nitrogen (N): 14.01 g/mol Oxygen (O): 16.00 g/mol

Calculate: [ 9 \times 12.01 \text{ (C)} + 13 \times 1.008 \text{ (H)} + 1 \times 14.01 \text{ (N)} + 3 \times 16.00 \text{ (O)} ]

[ = 108.09 \text{ (C)} + 13.104 \text{ (H)} + 14.01 \text{ (N)} + 48.00 \text{ (O)} ]

[ = 183.204 \text{ g/mol} ]

So, the molar mass of adrenaline (C9H13NO3) is approximately 183.204 g/mol.
