Find the molar mass, M, for thallium sulfide: 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: Tl_2S Use the chemical formula to count the number of atoms, N_i, for each element:  | N_i  S (sulfur) | 1  Tl (thallium) | 2 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)  S (sulfur) | 1 | 32.06  Tl (thallium) | 2 | 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)  S (sulfur) | 1 | 32.06 | 1 × 32.06 = 32.06  Tl (thallium) | 2 | 204.38 | 2 × 204.38 = 408.76  M = 32.06 g/mol + 408.76 g/mol = 440.82 g/mol
