Find the molar mass, M, for strontium sulfate: 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: SrSO_4 Use the chemical formula to count the number of atoms, N_i, for each element:  | N_i  O (oxygen) | 4  S (sulfur) | 1  Sr (strontium) | 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)  O (oxygen) | 4 | 15.999  S (sulfur) | 1 | 32.06  Sr (strontium) | 1 | 87.62 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)  O (oxygen) | 4 | 15.999 | 4 × 15.999 = 63.996  S (sulfur) | 1 | 32.06 | 1 × 32.06 = 32.06  Sr (strontium) | 1 | 87.62 | 1 × 87.62 = 87.62  M = 63.996 g/mol + 32.06 g/mol + 87.62 g/mol = 183.68 g/mol
