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 = \frac{mass of morphine}{mass of opium} x 100
                             = \frac{0.059}{0.685} x 100 = 8.6 %

An atom of 132sn has a mass of 131. 917760 amu. mass of1h atom = 1. 007825 amu mass of a neutron = 1. 008665 amu. calculate the
Lelechka [254]

The mass defect in amu/atom is 11.928.

The mass defect is the discrepancy between the nucleus of an atom's anticipated mass and its actual mass. This discrepancy is due to the binding energy of a system, which might manifest as excess mass.

The nucleus must be robustly spherical as expected for a doubly magical nucleus because the stripped neutron fell into a distinct orbital shell above the closed inner shells of tin-132 after the researchers examined the energy and angular distribution of the particles.

Mass of atom = 131.917760 amu

Mass of proton = 1.007825 amu

Mass of neutron = 1.008665 amu

Sn atom has 50 protons and 69 neutrons.

Mass defect = Mp + Mn - MA

                    = 50 × 1.007825 + 69 × 1.008665 - 131.917760

                    = 50.39125 + 69.597885 - 131.917760

                    = 11.928 amu/atom

Therefore, the mass defect in amu/atom is 11.928.
