Find the molar mass, M, for thallous nitrate: 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: TlNO_3 Use the chemical formula, TlNO_3, to count the number of atoms, N_i, for each element:  | N_i  N (nitrogen) | 1  O (oxygen) | 3  Tl (thallium) | 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)  N (nitrogen) | 1 | 14.007  O (oxygen) | 3 | 15.999  Tl (thallium) | 1 | 204.38 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)  N (nitrogen) | 1 | 14.007 | 1 × 14.007 = 14.007  O (oxygen) | 3 | 15.999 | 3 × 15.999 = 47.997  Tl (thallium) | 1 | 204.38 | 1 × 204.38 = 204.38  M = 14.007 g/mol + 47.997 g/mol + 204.38 g/mol = 266.38 g/mol
