Find the molar mass, M, for 3-fluoroisonicotinaldehyde: 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_6H_4FNO Use the chemical formula, C_6H_4FNO, to count the number of atoms, N_i, for each element:  | N_i  C (carbon) | 6  F (fluorine) | 1  H (hydrogen) | 4  N (nitrogen) | 1  O (oxygen) | 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) | 6 | 12.011  F (fluorine) | 1 | 18.998403163  H (hydrogen) | 4 | 1.008  N (nitrogen) | 1 | 14.007  O (oxygen) | 1 | 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)  C (carbon) | 6 | 12.011 | 6 × 12.011 = 72.066  F (fluorine) | 1 | 18.998403163 | 1 × 18.998403163 = 18.998403163  H (hydrogen) | 4 | 1.008 | 4 × 1.008 = 4.032  N (nitrogen) | 1 | 14.007 | 1 × 14.007 = 14.007  O (oxygen) | 1 | 15.999 | 1 × 15.999 = 15.999  M = 72.066 g/mol + 18.998403163 g/mol + 4.032 g/mol + 14.007 g/mol + 15.999 g/mol = 125.102 g/mol
