Question

What is the mass percentage of C in morphine, C₁₇H₁₉NO₃?

Answer 1

Answer:

2 C₁₇H₁₉NO₃ + H₂SO₄ → Product

Moles of H₂SO₄ = M x V(liters) = 0.0116 x 8.91/1000 = 1.033 x 10⁻⁴ mole

moles of morphine = 2 x moles of H₂SO₄ = 2.066 x 10⁻⁴

Mass of morphine = moles x molar mass of morphine = 2.066 x 10⁻⁴ x 285.34

= 0.059 g

percent morphine =

= = 8.6 %

Answer 2

Explanation:

The molar mass of morphine is

285.34

. It contains 72% carbon content

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