Question

Chem 30A Practice for Exam 3 1. Oxycodone is a semi-synthetic, morphine-like opioid alkaloid with analgesic activity. Its formula is C18H21 NO4. What is its molar mass in g? [Atomic masses: C, 12.011 amu; H, 1.00794 amu; N, 14.0067 amu; O, 15.9994 amu]

Answer 1

Solution :- Molecular formule of Ony Codone is : C18H2, NO. Given: Atomic mars af C = 12.011 amu Aromi mars af H=1.00794 amy Atome marsay N = 14-0067 amu Asonic mars of 0 = 15.9994 amu VI . Molar mass af (18 H2, Nooy = 18x Atomic mars of C+ 21x atomes mars af H+ Armic mars af Nt 4x atomic mess of angen = 18X 12-011 +21 X 1.00794 +14.0067 + 4X 15.9994 = 216.198 +21.16674714.0067+63.9976 = 315.369 g/mol molar mass = (315-369 g/mol
