The molar mass of morphine is $285.34$ $g*mol^-1$ . It contains 72% carbon content by mass.

Given a formula of $C_17H_19NO_3$ , the percentage by mass of carbon is:

$=$ $"Mass of carbon"/"Molar mass of morphine"$

$=$ $(17xx12.01*g*mol^-1)/(285.34*g*mol^-1)xx100%$ $=$ $72%$

Because this is one of the most powerful pain-killing drugs known, some 500,000 kg of morphine is produced annually by poppy farming.
