Question

Now that you have exercised, walked your

jackalope, made cookies, and had juice, you
decide on a nap. Your body uses melatonin to
tell your brain and body that it's ready to sleep
or nap. Melatonin has the chemical formula
C13H16N2O2. The amount in your body at any
time is very small - less than 10 milligrams
(0.01 g)! Convert the melatonin to moles so
you can rest

Answer 1

Answer: The moles of melatonin are 0.000043

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number
of particles.

To calculate the moles, we use the equation:

Given mass of melatonin = 0.01 g

Molar mass of melatonin
= 232.28 g/mol

Thus the moles of melatonin in 0.01 g are 0.000043
