🤓 Based on our data, we think this question is relevant for Professor Karlin's class at JHU.

$\overline{)\mathbf{mass}\mathbf{}\mathbf{percent}\mathbf{=}\frac{\mathbf{mass}\mathbf{}\mathbf{element}}{\mathbf{mass}\mathbf{}\mathbf{compound}}\mathbf{\times}\mathbf{100}}$

**For morphine, C _{17}H_{19}NO_{3}:**

$\overline{)\mathbf{mass}\mathbf{}\mathbf{percent}\mathbf{}\mathbf{O}\mathbf{=}\frac{\mathbf{mass}\mathbf{}\mathbf{O}}{\mathbf{mass}\mathbf{}{\mathbf{C}}_{\mathbf{17}}{\mathbf{H}}_{\mathbf{19}}{\mathbf{NO}}_{\mathbf{3}}}\mathbf{\times}\mathbf{100}}$

mass O = 16.00 g/mol

mass morphine = 285.332 g/mol

Calculate the percentage by mass of oxygen in the following compounds.

morphine, C_{17}H_{19}NO_{3}
