Result
![Find the molar mass, M, for sertraline: M = sum _iN_im_i Plan: • Write the chemical formula and gather atomic masses from the periodic table. • Determine values for N_i and m_i using these items. • Finally, compute the mass. Write the chemical formula: C_17H_17Cl_2N Use the chemical formula to count the number of atoms, N_i, for each element: | N_i C (carbon) | 17 Cl (chlorine) | 2 H (hydrogen) | 17 N (nitrogen) | 1 Look up the atomic mass, m_i, in g·mol^(-1) for each element in the periodic table: | N_i | m_i/g·mol^(-1) C (carbon) | 17 | 12.011 Cl (chlorine) | 2 | 35.45 H (hydrogen) | 17 | 1.008 N (nitrogen) | 1 | 14.007 Multiply N_i by m_i to compute the mass for each element. Then sum those values to compute the molar mass, M: Answer: | | | N_i | m_i/g·mol^(-1) | mass/g·mol^(-1) C (carbon) | 17 | 12.011 | 17 × 12.011 = 204.187 Cl (chlorine) | 2 | 35.45 | 2 × 35.45 = 70.90 H (hydrogen) | 17 | 1.008 | 17 × 1.008 = 17.136 N (nitrogen) | 1 | 14.007 | 1 × 14.007 = 14.007 M = 204.187 g/mol + 70.90 g/mol + 17.136 g/mol + 14.007 g/mol = 306.23 g/mol](../image_source/29f3cd434d9679bcd66d1283bf63f3fe.png)
