Answer: The moles of melatonin are 0.000043
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
Answer:
Explanation:
Data:
MM = 848.952 g/mol
c = 4.0 x 10⁻⁶ g/L
V = 1 L
Calculations:
