Find the molar mass, M, for 6-ethoxy-2-naphthaleneboronic acid: 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_10H_6OCH_2CH_3B(OH)_2 Use the chemical formula, C_10H_6OCH_2CH_3B(OH)_2, to count the number of atoms, N_i, for each element:  | N_i  B (boron) | 1  C (carbon) | 12  H (hydrogen) | 13  O (oxygen) | 3 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)  B (boron) | 1 | 10.81  C (carbon) | 12 | 12.011  H (hydrogen) | 13 | 1.008  O (oxygen) | 3 | 15.999 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)  B (boron) | 1 | 10.81 | 1 × 10.81 = 10.81  C (carbon) | 12 | 12.011 | 12 × 12.011 = 144.132  H (hydrogen) | 13 | 1.008 | 13 × 1.008 = 13.104  O (oxygen) | 3 | 15.999 | 3 × 15.999 = 47.997  M = 10.81 g/mol + 144.132 g/mol + 13.104 g/mol + 47.997 g/mol = 216.04 g/mol
